Berthold Stoeger 691d9e86de cleanup: implement index_of() and index_of_if() generics
Search the index of an item in a container. Compare by
equality or a lambda. The lack of these have annoyed me for a
long time. Return the index of the first found element or
-1 if no element found.

Currently, only supports random-access operators. Might be
trivially changed for forward iterators.
