Rugged::SubmoduleCollection#[]

Lookup +submodule+ by +name+ or +path+ (they are usually the same) in
+repository+.

Returns +nil+ if submodule does not exist.

Raises <tt>Rugged::SubmoduleError</tt> if submodule exists only in working
directory (i.e. there is a subdirectory that is a valid self-contained git
repository) and is not mentioned in the +HEAD+, the index and the config.
