(*) Fixed up the BOLD_ode -- takes globals now to speed up iteration-by-iteration computations [set once in SetBOLDParameters]
(*) Tweaked how MorrisLecar works, including downsampling and BOLD signal evaluation
(*) plot_BOLD_response now shows the period discarded and the detrended signal in a seperate subplot
(*) plot_V goes into freeform mode when more than 9 nodes
(*) SetAdjacencyMatrix now has more options, including a "randombinary"
(*) SimulateBOLD is no longer needed -- all code is in MorrisLecar
