Appending

Path append (const Path& pa, [string connector = "--", [bool assign = true]])

Function

Appends pa to *this using connector to join them and returns the resulting Path. If assign == true, then the return value is assigned to *this, otherwise, *this remains unchanged. If necessary, a const version could be added, for const Paths.
