Magic Missile

Description:
This is a spell in the spirit of the Baldur's Gate spell Magic Missile. This spell creates one missile per level of the ability, which darts forth from the wizard's finger-tip to unerringly strikes its target, dealing X damage per missile.
This will go up to at least 100 missiles. I tested that, but thought going any further was ridiculous.

endfunctionSpell Requirements:
1. A vJass preprocessor (If you don't have one you can download one from wc3campaigns.net)
How to implement this in your map:
1. Copy the CSCache and MagicMissile triggers to your map. (If you have CSCache, don't worry about it)
2. Copy the unit called Missile in the object editor.
3. Copy the ability called Magic Missile in the object editor.
