Class URLopener

Known Subclasses:
FancyURLopener

Class to open URLs. This is a class rather than just a subroutine because we may need more than one set of global protocol-specific options. Note -- this is a base class for those who don't want the automatic handling of errors type 302 (relocated) and 401 (authorization needed).
