Installing and using via python

[hyanwong]

We would like a fast NJ implementation to use from python. I see there is a pydecenttree folder, but no instructions for installation. Indeed, there seem not to be any instructions from compilation from source either.

A pip install -e pydecenttree results in:

../utils/timeutil.h:28:10: fatal error: 'decenttree_config.h' file not found
    #include <decenttree_config.h>

(this is on a Mac)

I guess I need to first run cmake . in the root directory to produce the decenttree_config.h file. When I do that (on a Mac), and then try pip install -e pydecenttree I get:
