[pdal] Building a PDAL pipeline in python

[Howard Butler]

The first problem is your cropping point is 

> POINT(671977.149785037 6621359.13979493)


but your coordinates for your file are in the box of 

>   Bounding Box:		1650000.00, 2079634.85, 1652999.99, 2081999.99


That's going to throw out all of the data and return a numpy array with zero points.

The second problem is there's a bug with loglevel = 9 that is causing the segfault. It has been fixed in master, but if you set your loglevel to something like 3 or 4 it should work.
