HyperParser uses PyParser. PyParser mostly gives information on the
proper indentation of code. HyperParser gives additional information on
the structure of code.

If the index given to the HyperParser is surrounded by a
bracket defined in openers (or at least has one before it),
return the indices of the opening bracket and the closing
bracket (or the end of line, whichever comes first).
If it is not surrounded by brackets, or the end of line comes
before the closing bracket and mustclose is True, returns None.
