 +### variousLsystems
 +An lsystem is generated each individual character is assigned a number. The code will go through the lsystem and placing the characters in number form into an array. The array is then assigned a name in an object. The object is then returned.

 +
 +#### Parameters
 +##### baseName
 +This is the base string for all the keys in the returned object. So, the names of the resulting object will be baseName+number. number starts from 0.
 +
 +##### n 
 +The amount of arrays in the returned object.
 +
 +##### patternLength
 +The total value of all the numbers in each array.
 +
 +##### rules
 +L-system rules. Object
 +
 +##### generations
 +
 +L-system generations. Number
 +
 +##### replacementValues
 +
 +The number each character should be assigned to.
 +
 +##### inputString
 +The string L-system should start with. The axiom of the L-system.
 +
 +##### allChars
 +All characters used by the L-system it will default to all the English alphabets if nothing is filled in.
