/* L-system OpenSCAD library by Hans Loeblich

Version 2.0
 - Now supports "M" move without draw
 - Also support position save "[" and restore "]"
 - Core functions have been completely rewritten and are about twice as fast using half the memory from before.
 - Rules now take the form of a single string per rule: "X=ABC"
 - Added new examples to demonstrate added features

This library is for creating L-systems, aka Lindenmayer System,
