 Currently with v.overlay, we can only use operators (and,or,not,xor) for
 extracting lines or polygons from feature A given feature area B. It would
 be nice to expand this option to include points as a possible Feature A
 class.

 Currently, If I wanted to select all points that do not fall within a
 given polygon, I would first have to create a vector area for the given
 region (v.in.region), then I would have to run v.overlay using  the 'not'
 operator to create an area feature that excludes the polygons of interest,
 than I would run v.select to select the points that fall within the new
 polygon.
