Functions to Explore L-Systems (Lindenmayer Systems)
Details
Lindenmayer or L-systems are parallel rewriting systems
which can be used to simulate biological forms and certain
kinds of fractals. Briefly, in an L-system a series of
symbols in a string are replaced iteratively according to
rules to give a more complex string. Eventually, the
symbols are translated into turtle
graphics for plotting. Wikipedia has a very good
introduction: https://en.wikipedia.org/wiki/L-system
This package provides basic functions for exploring L-systems.
