Odd --sortRegions keep issue

[dpryan79]

This was reported today internally. Sometimes computeMatrix will crash with:

Traceback (most recent call last):
 File "/package/deeptools-2.4.0/bin/computeMatrix", line 11, in <module>
   main(args)
 File "/package/deeptools-2.4.0/lib/python3.4/site-packages/deeptools/computeMatrix.py", line 430, in main
   cmo.sortMatrix(hm, args.regionsFileName, args.transcriptID, args.transcript_id_designator)
 File "/package/deeptools-2.4.0/lib/python3.4/site-packages/deeptools/computeMatrixOperations.py", line 621, in sortMatrix
   for k, v in regions[idx].items():

I have the full command so I'll have a look.

The problem only occurs with BED files that have a deepTools_group column. In this case, the regions are all stored in a list, rather than a dict, which is a bug.

This should now be fixed in the develop branch.
