Detailed Description

Stores a value of any type.

Examples of use: 

 {.cpp}
 Any uintVariable = 5u;
 Any floatVariable( 4.5f );
 Any strVariable( std::string( "Hello world" ) );
 uintVariable = 1u;
 unsigned int variable = AnyCast< unsigned int >( uintVariable );
 if ( typeid( int ) == uintVariable.GetType() )
