A Map from Elements to Axioms.

An LSystem is an Axiom and a set of Rules.

L-System constructor.

lSystem "F+F+F" [('F',"F-F+F")]

Rule lookup.

Rule application.

n iterations of the specified LSystem.

let f p q n = expand (lSystem p q) n
f  "A" [('A',"AB"),('B',"A")] 5 == "ABAABABAABAAB"
f "0" [('1',"11"),('0',"1[0]0")] 3 == "1111[11[1[0]0]1[0]0]11[1[0]0]1[0]0"
f  "A" [('A',"ABA"),('B',"BBB")] 3 == "ABABBBABABBBBBBBBBABABBBABA"
f  "F" [('F',"F+F-F-F+F")] 2 == "F+F-F-F+F+F+F-F-F+F-F+F-F-F+F-F+F-F-F+F+F+F-F-F+F"
f "F+F+F" [('F',"F-F+F")] 1 == "F-F+F+F-F+F+F-F+F"
