/*QUAKED func_bob (0 .5 .8) ?
A SOLID bmodel that gently moves back and forth
-------- KEYS --------
targetname : trigger entity (works with entity state system)
angle    : direction movement, use "360" for angle 0
height   : direction intensity (def=8)
count    : direction cycle timer (def=2s, minimum=1s)
waitmin  : Speed up scale (def=1) 1+=non linear
waitmin2 : Slow down scale (def=0.75)
delay    : Starting time delay (def=0, -1=random)
style 	 : If set to 1, starts off and waits for trigger
_dirt       : -1 = will be excluded from dirtmapping
_minlight   : Minimum light level for any surface of the brush model
_mincolor   : Minimum light color for any surface (def='1 1 1' RGB)
_shadow     : Will cast shadows on other models and itself
_shadowself : Will cast shadows on itself
-------- SPAWNFLAGS --------
STARTOFF : Starts off and waits for trigger - DISABLED, Ripped out ESTATE System (RennyC)
-------- NOTES --------
