/*checkpoint_spawner- Custom entity for spawning a new point_checkpoint with spawn fx
	This entity only triggers when survival mode is active.
	Entity supports all the keyvalues that point_checkpoint does

	Installation:-
	- Place in scripts/maps
	- Add
	map_script checkpoint_spawner
	to your map cfg
	OR
	- Add
	#include "checkpoint_spawner"
	to your main map script header
	OR
	- Create a trigger_script with these keys set in your map:
	"classname" "trigger_script"
	"m_iszScriptFile" "checkpoint_spawner"

	Keys (these are optional):-
	"sprite" "sprites/path/to/sprite.spr"	- customise the sprite for the spawn fx
	"model" "models/path/to/model.mdl"		- customise the checkpoint model
	"startsound" "path/to/sound.wav"		- customise spawning start sound fx
	"endsound" "path/to/sound.wav"			- customise spawning end sound fx
- Outerbeast
