Detailed Description

This class is a modified version of the model of a gastric Interstitial Cell of Cajal.

Reference publication is:

Corrias A, Buist ML. "Quantitative cellular description of gastric slow wave activity." Am J Physiol Gastrointest Liver Physiol. 2008 Apr;294(4):G989-95. Epub 2008 Feb 14.

Modifications include:

simplified mitochondria dynamics (assumed mitochondrial potential is almost constant
ability to set K+ channels-affecting CO concentrations
ability to deflect a fraction of VDDR channels into the pacemaker unit.
