A particle stream!  It appears when triggered.  This entity is
one end of the stream, target another entity as the other end-point.
I used the info_notnull, but you should be able to target anything
(like monsters).

"target"   This entities origin is the end-point of the stream
"dmg"  1st Color  -  Use if you want a single color stream
"cnt"  2nd Color  -  Mixes particles of both colors
"noise"  Sound to play when triggered
