init file n_compounds accepting floats as inputs

[bryaniswright]

the error that i encountered was that i set the number of compounds to be 1.0 which is a float and not an integer and planckton-flow was unable to read this value. the exact error is pasted below.

Using environment configuration: Bridges2Custom
ERROR: Encountered error during program execution: ''float' object cannot be interpreted as an integer'

Execute with '--show-traceback' or '--debug' to get more information.

@jennyfothergill Would adding a docstring and/or hashed comment to the init.py file be a good fix?

@gwenwhite sorry I didn't see this sooner! Yes, a comment line is probably the best way to fix it. Alternatively we could cast any value entered in n_compounds to int. I prefer your suggestion though :)
