/**** LEAPFROG SYSTEM ****
Thread maps\_leapfrog::leapfrog() on any AI that uses a chain of nodes.
Make sure to check the NOT_CHAIN check box on each node in the chain to allow chains to merge or loop.
You need at least two chains for this to look good.
level.leap_delay_min and max determines how fast they try to advance.
set script_delay on a node to have the ai use a delay instead of waiting for a leap notify.
script_delay = 0 will make them run past that node before going to the next one.
