Produces a bifurcation diagram for the discrete logistic. Program is from Roughgardens book. [output]    logist_d.m
Converts a string representation of an equation into the appropriate form for operating on each individual element of a vector, instead of treating it as a matrix operation. Program is from Roughgardens book.
