closes #2782
Initial commit of mixed cython_numpy wrapper
Small note on installation and usage
Added setup.py to cython_numpy
A little test to give it a spin...
A couple of ignores for cython_numpy
Wrapped d2dtf()
Modified test to include d2dtf()
Cleaned-up build processto play nicely with other approaches.

This was modified by @eteq on import into astropy to not affect astropy core package files.

Conflicts:
	.gitignore
	setup.py
Removed README.md from cython_numpy
For now, test with erfa.cython_numpy
Better broadcasting example
Vectorize all d2dtf() imputs.

For later automation, it is easier to have all inputs vectorized.
Added aper()

Just because one of its parameters is an input and an output at the
same time. And it also uses the complex eraASTROM structure.
Added a test for aper()
Postfixed all output arguments with '_out'
cdef and assign all C arguments before use
Use copy constructor array() and broadcast_arrays()...

…instead of empty() and copyto()
