If something is blocking the spawnspot, this will telefrag it as long as it's not a living entity (flags2&FL_ALIVE)

You can set up as many spots as you want for it to spawn at and it will cycle
between these.  Make them classname func_monsterspawn_spot and
their spawnername has to match this entity's spawnername.
You can control the order in which they are used by setting thier
aflag (1, 2, 3, etc- there is NO ZERO, that's for you designers!)
You should give the spawner an aflag too if you want it's origin
included in the cycle of spawning, but if there are no spawn spots (just a spawner), no aflag is needed anywhere.

WARNING!!!  If you forget to put spawnspots and you give the spawner a spawnername, it will go into an infinite loop and the Universe will cease to exist!

If you only want monsters to spawn at the monster spawner origin, then don't worry about aflags or the spawnername, it will know... It's that cool.

The Monsters will be spawned at the origin of the spawner (and/or spawnspots), so if you want them not to stick in the ground, put this above the ground some- maybe 24?  Make sure there's enough room around it for the monsters.

ONDEATH = only spawn the new monster after the last has died, defaults to FALSE (doesn't wait)
TRIGGERONLY = Will only spawn a monster when it's been used by a trigger.  The default is continous spawning.
wait = time to wait after spawning a monster until the next monster is spawned, defaults to 0.5 seconds. If there are multiple spawn spots, this will be the time between cycles (default 0.5)
cnt = number of monsters, max to spawn, defaults to 17 (no reason, just like that number!)	If there are multiple spots, this should be the total off ALL the spots, including the spawner itself.
aflag = order in the spawning cycle
spawnername = spawnspots to look for- be sure to make spawnspots!
targetname = not needed unless you plan to activate this with a trigger

There will be a test on this on Thursday.  Interns are NOT exempt.

All this does is mark where to spawn monsters for a spawn spot.

You can set any monster type for each spawnspot.

Just make the spawnername of this entity equal to the spawnername of the spawner and the spawner will cycle through all it's spawnspots in the world.

If you don't set the aflag, the spawn spot will NOT be used.

Note that if you set a trigger to activate this spawnspot, you can have it turn on and be included in the spawner's cycle, but you still always have to set the aflag.

aflag = order in the spawning cycle, you MUST set this, or it's useless.
cnt = number of monsters this spot will spawn, defaults to 17.
spawnername = this HAS to match the spawner's spawnername!
wait = how long the minimum interval should be between monster spawns for THIS spot.
targetname = used if you want this to wait to be activated by a seperate trigger before being included in the spawning cycle.
