Copied from configuration, renaming Configuration -> XMLReader, and 

Configurator -> XMLerator.

Included typedefs so that existing applications can simply include
XMLReader.hpp in place of configuration.hpp.

// What about this =============================================================

// The XMLReader module provides a platform for reading configuration files
// (or string data) containing well-formed xml and mapping that data to program
// variables.
// The idea is to provide the ability for an object or application to provide
// a modular "XMLReader" object that models a hierarchical collection of
// "settings" that can be represented easily in code and in xml.
//
// The following is an example model of a XMLReader in code and that same
// XMLReader fully populated in xml.
//
// The code might look like this...
//
// int IntValue, DefaultInt = 3;
// double DblValue, DefaultDbl = 3.14159;
// bool BooleanValue, DefaultBool = false;
// string StringValue, DefaultString = "NoStringHere";
//
// SpecialConfigurator : public XMLReaderHandler { // Create a special handler to build a list
// ...
// public:
//
// XMLReaderHandler& Startup(XMLReaderElement& E) { // This function returns a handy handler to
// return MyStartupXMLReaderHandler; // (re) initialize this handler ;-)
// }
//
// void Operator()() { // Each time the configurator is called
// ...
// }
//
// int Attribute1; // these items are interpreted and added
// double Attribute2; // to the list. A XMLReaderHandler COULD
// string Attribute3; // do something entirely different though ;-)
// string Contents;
// ...
// } Special;
//
// XMLReaderElement SampleConfig("SampleConfiguration"); // Define a sample config (doc element)
// SampleConfig // Populate the SampleConfig
// .atStartCall(Special.Startup())
// .Element("Integer", IntValue, DefaultInt).End() // Link an element to an int w/ default.
// .Element("Double", DblValue, DefaultDbl).End("Double") // Link an element to a dbl w/ default.
// .Element("String", StringValue, DefaultString).End("String") // Link an element to a string w/ default.
// .Element("ComplexElements") // Create a sub element.
// .Element("Complex1") // Sub element Complex1 has attributes.
// .Attribute("IntAtt", IntValue, DefaultInt) // Complex1 has an integer attribute.
// .Attribute("DblAtt", DblValue, DefaultDbl) // Complex1 has a dbl attribute.
// .Element("IntAtt", IntValue).End() // IntAtt can also be set by a sub element.
// .Element("DblAtt", DblValue).End() // DblAtt can also be set by a sub element.
// .End() // That's it for Complex1.
// .Element("Complex2") // Create the Complex2 sub element.
// .Attribute("C2I", IntValue, DefaultInt) // C2I attribute.
// .Attribute("C2D", DblValue) // C2D attribute - no default.
// .Attribute("C2S", StringValue, DefultString) // C2S attribute - string w/ default.
// .End("Complex2") // End of element throws if doesn't match.
// .Element("Complex3", Special.Contents) // Element 3 using a special configurator.
// .Attribute("A1", Special.Attribute1) // Set A1 and A2 and A3 and when the
// .Attribute("A2", Special.Attribute2) // element has been completed, Special()
// .Attribute("A3", Special.Attribute3) // will be called to record the entries.
// .atEndCall(Special) // Here's where we register the handler.
// .End() // Closing Complex3 to be ice.
// .End() // Closing ComplexElements to be nice.
// .End(); // Closing SampleConfiguration to be nice.
//
// The XML might look like this...
//
// <SampleConfiguration>
// <Integer>10</Integer>
// <Double>2.4</Double>
// <String>This is a sample string</String>
// <ComplexElements>
// <Complex1 IntAtt="4" DblAtt="2.1324">
// <IntAtt>24</IntAtt> <!-- changed IntAtt -->
// </Complex1>
// <Complex2 C2I='3' C2D='5.14' C2S='Some "string" we like' />
// <Complex3> stuff in here </Complex3>
// <Complex3> Another instance </Complex3>
// <Complex3> Each one gets passed to Special() on activation </Complex3>
// <Complex3> This way, Special() can build a list or some other </Complex3>
// <Complex3> interesting thing with all of these. </Complex3>
// <ComplexElements>
// </SampleConfiguration>
//

// The way data gets into an element tree is that it is Interpret()ed
// recursively. The data is loaded into a XMLReaderData object which
// is passed to the top Element. That element interpretes the data, moves
// the interpretation pointers, and passes the data on to it's subordinate
// elements in turn. They do the same recursively. When the last sub -
// element has had it's way with the data, the interpretation process is
// complete. The XMLReaderData object will contain the original data
// and a log of anything that happened during the interpretation process.
//
// Each time an element is asked to Interpret() data, it calls any atStart
// configurators, translates any attributes, then either translates it's
// contents or passes the data to it's children, then calls any atEnd
// configurators.
//
// To ensure that the correct default values are used the Initialize() is
// always called on all internal attributes and elements before any data is
// interpreted. To prevent this from being inefficient, a boolean flag is
// kept in each element to keep track of whether it is clean and if it is
// then the call to Initialize will simply return (skipping subordinate
// elements along the way).
//
// Interpret returns true if this object found itself at the current
// Data.Index and false if not. This helps keep the recursive parsing
// code simpler ;-)

//// XMLReader Mnemonic ////////////////////////////////////////////////////
//
// A Mnemonic allows the actual contents of an element or attribute to be
// exchanged for a different "named" value to help eliminate "magic numbers"
// and "secret codes" from configurations. One way this might be used is to
// map an enumeration to the appropriate integer values, or things like YES and
// NO to boolean true and false (respectively) when turning on/off program
// options.

class XMLReaderMnemonic { // Mnemonics
private:
std::string myName; // What is the Mnemonic?
std::string myValue; // What is the translation?

public:
XMLReaderMnemonic(std::string Name, std::string Value); // To make one, provide both parts.
bool test(std::string Name); // Test to see if this Mnemonic matches.
std::string Value(); // If it does then we will need it's value.
};

//// XMLerator //////////////////////////////////////////////////////////////
//
// An XMLerator is a "functor" or "closure" or "callback" that can be used to
// support sophisticated interpretation options. The most basic and necessary
// of these is support for list building. Consider an object created to contain
// a list of records where each record might be represented as a collection of
// attributes and elements. The object would have data elements mapped to the
// attributes and elements in the configuration and then control elements which
// are functors for initializing the list and storing new entries as they are
// completed. The object here is a pure virtual prototype.

class XMLerator { // XMLerators exist
public:
virtual void operator()(XMLReaderElement& E, XMLReaderData& D) = 0; // Pure virtual configurator.
virtual ~XMLerator() {} // Virtual dtor keeps warnings away.
