Revised Dendrite, Direct to Soma, and Membrane Potential formulas used.

Output of the simulation is not producing spiking the way wanted but all formulas from the paper are included and updated formulas for current are included.  Updated formulas in the form of "V = -(W + V) * (e ** (-t/tau)) + W" are from https://math.stackexchange.com/questions/1009989/how-to-take-the-integral-of-a-derivative-to-obtain-desired-result .  I will work on tuning the code to produce results as wanted
