Numpy -> nda::array cheat sheet?

[mgraczyk]

It would be very helpful to provide a cheat sheet table at the top of the array.h header file. Something that shows how to do an equivalent numpy, Matlab, or Eigen operation using array.h

I was recently confused by slicing vs cropping. Something like this would help a lot

numpy	nda::array
x[:, :, 0]	x(_, _, 0)
x[:, :, [0]]	x(_, _, range(0, 1))

etc
