Support for operator < and operator >

[ashhasthantra]

Currently, cpp_python_operator_map source/function.cpp doesn't include operator < and operator >. My C++ code base provides operator overloading for < and >. Having them as part of the cpp_python_operator_map list would be really helpful.

Can you please provide support for operator < and operator > overloading?

Thanks.

Probably, this should also include other comparison operators as well: <= and >=?!
