/*
USAGE OF "cvardef"
cvardef replaces the multiple lines of code used repeatedly in the setup areas of the script.
The function requires 5 parameters, and returns the set value of the specified cvar
Parameters:
	varname - The name of the variable, i.e. "scr_teambalance", or "scr_dem_respawn"
		This function will automatically find map-sensitive overrides, i.e. "src_dem_respawn_mp_brecourt"

	vardefault - The default value for the variable.  
		Numbers do not require quotes, but strings do.  i.e.   10, "10", or "wave"

	min - The minimum value if the variable is an "int" or "float" type
		If there is no minimum, use "" as the parameter in the function call

	max - The maximum value if the variable is an "int" or "float" type
		If there is no maximum, use "" as the parameter in the function call

	type - The type of data to be contained in the vairable.
		"int" - integer value: 1, 2, 3, etc.
		"float" - floating point value: 1.0, 2.5, 10.384, etc.
		"string" - a character string: "wave", "player", "none", etc.
