ENH: additional Map/HashTable constructors and ListOp functions

- construct Map/HashTable from key/value lists. - invertToMap() : like invert() but returns a Map<label>, which is useful for sparse numbering - inplaceRenumber() : taking a Map<label> for the mapper ENH: construct/reset CStringList for list of C-strings
