addition of point in polygon routines
This commit adds a set of new functions for determining whether a point P is located in a polygon given by its vertex points V. Both algorithms for the even-odd-rule and for the winding number calculation are implemented. The commit also fixes a few typos in the documentation of a few other routines.
