logisticmap 0.0.3

This gem implements: 1.) a logistic map function (#logistic_map), which is a discrete, non-linear, dynamic equation which can show - with proper parameters - chaotic behaviour with super-sensitivity to the initial parameters. Very small changes to initial parameters cause huge changes in the result (can be used as a PRNG as iterated over and over); 2.) A tent-map version of the logistic map (#logistic_points) which returns an array of Nth iterated values of several logistic maps with their initial X0 parameter ranging from 0 to 1 by user defined steps, showing curve-like properties when plotted.
