Made the print python 3 style. pep8 and link to memoryviews.

Put the pip installation first.

Improvements of the docs.

Split prototype part off a utility function to move the actual implementation to the end of the C file.

Misc typos

Found via `codespell`

Closes #1606.

Mention Typed Memoryviews in the Working with NumPy doc.

Updated the example for --annotate.

Increase the ccache size on travis from 100M to 150M as we've probably passed the limit already with all the tests that we have now.

Closes #2013.
