I would like to use your library to make a call such as

CanDispel(target, spellID)

e.g. if my spell is Cleanse, ID 4987 I could do something like CanDispel("focus",4987)

This would loop through my focus buffs and tell me true or false if my Cleanse would be wasted. I am having trouble figuring this out and any help is appreciated. Thanks!
