Rename CodeSnippets/lerpColor.pde to CodeSnippets/Gradient-Module/lerpColor.pde

Given 2 colours Colour1 and Colour2, LerpColour(colour1, colour2, x) allows you to compute a colour at x where x is a position at x distance from colour1 and 1/x distance from colour 2. So a colour at x = 0, will be a colour that is the same as colour1 while a colour at x = 1, will be a colour that is the same as colour2. X has to be between 0 and 1.

My plan is give 2 colours to lerpColour and having the whole 0 to 1 range of x computed and sent to the stroke() functions that assign the colour to the lines all over the screen. The increment of x (incx) will be linear and will be the function of 1/n where n is the number of lines to be printed. So if there are 500 lines, the function would be 1/500 and incx or x would be 0.002.
