usage example

cd example/
trackHub_generator.py -o mm10_upload mm10/

Parses mm10/ directory and writes tracksDb.txt to mm10_upload/ It also links (symbolic) all used files to mm10_upload/ for easy cloud upload afterwards.

Recognized subdirs (in the example under mm10/)

Allowed directory names: *.multiwig
                   *.composite
                   *.super

Only one nesting level is supported by UCSC! So only super containers can hold one 
level of multiwig or composite containers, not more! 

composite/ multiwig containers can only contain tracks.

The toplevel can contain tracks (not related to any container)

Current code only supports *.bw|*.bigwig or *.bb|*.bigbed tracks!
