-underlying optical stimulation of a channelrhodopsin-2 positive

-For best results, open directory in ipython notebook and load
-"Optical Stimulation". Otherwise, refer to "Optical Stimulation.py".

-20150518 Updates from Ted Carnevale:
-1. The gbar parameters of the mechanisms specified by these files
-ca.mod kca.mod km.mod kv.mod na12.mod na16.mod na.mod are now the
-actual channel densities. This eliminates a spurious temperature
-dependency of the effective channel density.
-2. These same files are now threadsafe, and use efun rather than
-vtrap0 to deal with singularities. See the mod files for more
-information.
-
-20150524 Update from Ted Carnevale: Changed integration method from
-euler to derivimplicit which is appropriate for simple ion
-accumulation mechanisms. See Integration methods for SOLVE statements
