Why doesn't IsCentral work for group elements?  It's not hard to turn the element into a group and then IsCentral works, but it seems silly that it doesn't work, considering that the help says

IsCentral( M, obj )
IsCentral returns true if the object obj, which must either be an element or a magma, commutes with all elements in the magma M.
