Detailed Description

template<class IT>
struct PyItPatch< IT >

This class provides some pathces for an iterator.

Some c++ classes have methods to return iterators instead of vectors. In this case people need to use iterators directly. PyKernel addes next() and patches eq()/__ne__() instead. Then one can use the iterator like as a python iterator.
