In some cases it would be helpful to parse comments from BNGL files

[jonrkarr]

bionetgen.bngmodel nicely parses models. In some cases, it may be helpful to parse the comments out of files.

For example, the comment of Vec is currently parsed to None

begin parameters
 Vec   1000*Vcell # Volume of extracellular space around each cell (1/cell density)
end parameters

model = bionetgen.bngmodel(...)
model.parameters['Vec'].comment

The comments are not parsed at all right now due to how parsing works currently (conversion to an XML file and reading off of that). XML conversion rips out all comments so it's not possible to parse the comments with this method. We are working on a new parsing method right now and once that's done, all comments will be parsed and will be added to .comment attribute. I'll update the issue as I make progress on this.
