/************************************************************************
* The XML parser processes an XML file into a tree data structure composed of *
* ezxml_t nodes. Each ezxml_t node represents an XML element. For example *
* <a> <b/> </a> will generate two ezxml_t nodes. One called "a" and its *
* child "b". Each ezxml_t node can contain various XML data such as attribute *
* information and text content. The XML parser provides several functions to *
* help the developer build, traverse, and free this ezxml_t tree. *
* *
* The function ezxml_parse_file reads in an architecture file. *
* *
* The function FindElement returns a child ezxml_t node for a given ezxml_t *
* node that matches a name provided by the developer. *
* *
* The function FreeNode frees a child ezxml_t node. All children nodes must *
* be freed before the parent can be freed. *
* *
* The function FindProperty is used to extract attributes from an ezxml_t node. *
* The corresponding ezxml_set_attr is used to then free an attribute after it *
* is read. We have several helper functions that perform this common *
* read/store/free operation in one step such as GetIntProperty and *
* GetFloatProperty. *
* *
* Because of how the XML tree traversal works, we free everything when we're *
* done reading an architecture file to make sure that there isn't some part *
* of the architecture file that got missed. *
