Increase available information on invocation error.

Cache C/C++ compilation

Fixed typo in NumPy example which prevented compilation

Refactoring bind_vector to take std::string

Refactoring bind_vector to take std::string to avoid capture of potentially temporary char const * when calling vector_if_insertion_operator

Fixing VC build, apparently MSVC implementation of std::is_default_constructible had no bool() operator

Adding documentation for value_error. Fixing various formatting issues. Removing redundant binding for C++ style methods. Adding bindings for iterator and slicing protocol. Extending examples.

Adding Python-style modifiers for vector. Wrapping has_insertion_operator_implementation in _MSC_VER ifdef’s. Adding ‘!=0’ instead of bool cast’s.

add extra constructors in numpy.h

Compilation issue fixed
