Namespace: Deedle.Keys

Helper type that can be used to get ICustomKey for any object (including objects that actually implement the interface and tuples)

Static member	Description
`Get(key)` Signature: key:obj -> ICustomKey	Returns `ICustomKey` instance for the specified key. If the specified key implements `ICustomKey`, then it is just returned; if it is a tuple, we use special key for tuples otherwise, it must be a primitive key so we just return it
`GetForTuple(tuple)` Signature: tuple:obj -> ICustomKey
