Is there a method in the Ruby array object that gives anything like a
"contains?" method, to test if an object is already in the Array?
For the time being, I've extended the Array class as follows:
I wondered if this was a good way, or if there was already something in
the API that allowed for this. I couldn't seem to find anything..

Returns the index of the first object in *self* such that is == to *obj*.
Returns nil if no match is found.
a = [ "a", "b", "c" ]
a.index("b") #=> 1
a.index("z") #=> nil
