#5 Assignment operator should be return by reference

[Gaurav]

in File tinyxml.h
In TiXmlHandle class assignment operator should return by reference.

Here is diff.

- TiXmlHandle operator=( const TiXmlHandle& ref ) { this->node = ref.node; return *this; }
+ TiXmlHandle& operator=( const TiXmlHandle& ref ) { this->node = ref.node; return *this; }
