nxutils has been removed from master because it is completely redundant to the Path functionality that has been in matplotlib since 0.98.  In the process of porting to Python 3, I felt it was important to reduce code duplication, because every additional line requires additional testing.

That said, there seems to be a lot of push back on this.  We can reinstate it, but I would suggest raising DeprecationWarnings for one release and then removing it entirely in the next.

Huh? Nxutils removed? Then how am I still using points_inside_poly? And, if I remember right, Path uses that to calculate contains().

All the data continuously generated in your IT infrastructure 
contains a definitive record of customers, application performance, 
security threats, fraudulent activity, and more. Splunk takes this 
data and makes sense of it. IT sense. And common sense.
