/**
@subpage ticpp is a TinyXML wrapper that uses a lot more C++ ideals.
It throws exceptions, uses templates, is in its own name space, and
<b>requires</b> STL (Standard Template Library). This is done to ease the use
of getting values in and out of the xml.

If you don't perfer to use some of the concepts just don't use it.
It is just a wrapper that extends TinyXML. It doesn't actually change
any of TinyXML.
