 *   Returns the Perlin noise value at specified

 *   Perlin in the 1980s and been used since in 
 *   graphical applications to produce procedural 
 *   textures, natural motion, shapes, terrains etc.
 * 
 *  
 *   The main difference to the random() function is 
 *   that Perlin noise is defined in an infinite 
 *   n-dimensional space where each pair of coordinates 
 *   corresponds to a fixed semi-random value (fixed 
 *   only for the lifespan of the program; see the 
 *   noiseSeed() function). p5.js can compute 1D, 2D 
 *   and 3D noise, depending on the number of 
 *   coordinates given. The resulting value will always 
 *   be between 0.0 and 1.0. The noise value can be 
 *   animated by moving through the noise space as 
 *   demonstrated in the example above. The 2nd and 3rd 
 *   dimension can also be interpreted as time.
 * 
 *   The actual noise is structured similar to an audio 
 *   signal, in respect to the function's use of 
 *   frequencies. Similar to the concept of harmonics 
 *   in physics, perlin noise is computed over several 
 *   octaves which are added together for the final 
 *   result. 
 * 
 *   Another way to adjust the character of the 
 *   resulting sequence is the scale of the input 
 *   coordinates. As the function works within an 
 *   infinite space the value of the coordinates 
 *   doesn't matter as such, only the distance between 
 *   successive coordinates does (eg. when using 
 *   noise() within a loop). As a general rule the 
 *   smaller the difference between coordinates, the 
 *   smoother the resulting noise sequence will be. 
 *   Steps of 0.005-0.03 work best for most 
 *   applications, but this will differ depending on 
 *   use.

 *   intensity of the noise, whereas higher octaves 
 *   create finer grained details in the noise 
 *   sequence. 
 * 
 *  
 *   By default, noise is computed over 4 octaves with 
 *   each octave contributing exactly half than its 
 *   predecessor, starting at 50% strength for the 1st 
 *   octave. This falloff amount can be changed by 
 *   adding an additional function parameter. Eg. a
