This library is intended to be used to create and load XML files to a C structure.
It is a 2-part software:
 - The first part is a C++ library that is used to parse and retrieve values from XML file, and create
   XML files from a list of specifications.
 - The second part is a python script that generates a C code to automatically create XML from a C structure, 
   fill the C structure from an XML file and compare an XML file with the C structure to find the common and
   and different items.

The xmlpp.py python script takes as input a header file describing C structures and generates the code for the 
automatic structure filling and XML creation. If more than one structure is present in the header
file, you must specify which one is the top one. 
Usage:
    xmlpp.py {headerFile.h} --struct {topStructure}
This will produce besides your {headerFile.h} two C++ files {headerFileProxy.h} and {headerFileProxy.cc} 
that you should include in your compilation.

The following functions are implemented in these 2 files:
   int xml_read_file_exampleStruct(const char* fileName);
   int xml_apply_exampleStruct(exampleStruct *ptr);
   int xml_test_exampleStruct();
   void* xml_start_compare_exampleStruct(exampleStruct *ptr);
   void* xml_next_compare_exampleStruct(exampleStruct *ptr);
   int xml_create_exampleStruct(exampleStruct *ptr, const char* fileName);
   const char* xml_getLastFatalError_exampleStruct();
