/* Routine for real variable SBX crossover based on the original implementation by Kalyanmoy Deb.
 * The following implementation is written in Javascript using functional programming, in my 
 * opinion, it's easier to understand than the original C version (procedural).
 *
 * Implementation by Tiago Peres França
 *
 * OBS1: Based on the following code and paper: https://gist.github.com/Tiagoperes/1779d5f1c89bae0cfdb87b1960bba36d
 *
 * OBS2: functions starting by "_." are from the functional library Lodash.
