 * This is the coordinate system:

 * |  z
 * | /

 * *------x
 *
 * turtle starts heading up (y axis)
 * +	turn left	(z)
 * -	turn right	(z)
 * ^	pitch up	(x)
 * &	pitch down	(x)
 * /	rotate right	(y)
 * \	rotate left	(y)
 *
 * this is a bit illogical, but it makes 2d and 3d compatible (using + and -)
 *
 * full rules have the form
 * module_name"("parameters...")" ":" constraint_expression "=>" expansion"," iterations ";"
 *
 * where "(parameters...)", ": constraint_expression", "expansion" and ", iterations"
 * are optional parts, i.e.
 *
 * A => ;
 *
  is a valid rule, which unconditionally removes all occurences of A.
