Added the relevant fields to be returned by querying the database. Also
added 'regulatory_feature' as an annotation feature.
Reorganized the annotation data to remove duplicate gene TSSes and such.
All TSS on query region are plotted. Also created variables for axis
margins.
add_annotations() plots multiple TSS of different genes.
Fixed order of functions so that the annotation collection is only
queried twice.
Removed MongoQuery stuff since it's not useful... Fixed the passing of
parameters to different methods.
Cleaned up some more. querying annotation once still doesn't work...
Merge branch 'master' of https://github.com/apfejes/epigenetics-software.git
Querying works again but method calling order isn't optimal. Started
plotting islands as well.
