Title: Various docstring corrections + fix an example

Hi,

This PR contains corrections in docstrings. In particular, there is a review of hough_line thanks to a private email of Emre Safak suggesting to add a note in the dosctring and to fix a bug in an example.

About the bug, the angles are in [-90,90] (by default). It was not the case in the original plot.
