Neuron Total Soma Membrane Potential (Ntsmp) calculation function

This is a function that calculates the total soma membrane potential for each individual neuron.  This code is a work in progress rough version that is not fully implemented, mainly I am showing what I am currently working on by posting this.  I understand that the Dpsc, Spsc, and Tsmp functions need to have rearranged calculations to solve for current and I am working on that.  Also, elements such as spike times (t), stmp weight adjustments, and other elements need to be added.
