How to use

This L-System grammer is similar to lsys (http://benvan.co.uk/lsys/ ).

F : draw forwards by "size"
+ / - : rotate by +/-"angle"
> / < : increase/decrease "size" by "DeltaSize"
) / ( : increase/decrease "angle" by "DeltaAngle"
[ / ] : push / pop state
! : negate "angle"
| : increment "angle" by 180(degree)
