API GetCraftSpellFocus

catalystName, number1 = GetCraftSpellFocus(index)
===Arguments===
:;index: - 1 to GetNumCrafts()
===Returns===
When called while the enchanting screen is open, this function returns which rod is required, if any. I don't know whether this function also applies to other types of crafts or spells.
Returns two values when a rod is required: a string that contains the name of the rod, and the number "1". I don't know what the "1" means.
Returns nil if no rods are required.
