This example simulates the slow wave activity in the 1D small intestine
(Longitudinal muscle (LM) and Interstitial Cells of Cajal (ICC)) and
generate a single dipole from the transmembrane potential gradients at each
element (refer Master Thesis Section 5.3 - A. Lin (2003)).
The cell model is based on Aliev et al. (2000) except for the excitation
parameter to create a decreasing frequency, conduction velocity and wavelength
profile. However, the transmembrane potential solution doesn't reach a steady state which is a limitation
of the cell model. An example of the transmembrane potentials at two specific times is given below. The
left figures are longitudinal muscle and the right figures are ICC layers.
