# create an authen object

$authen->forget_verification;WeBWorK::Authen is the base class for all WeBWorK authentication classes. It provides default authentication behavior which can be selectively overridden in subclasses.
This subroutine consults the given WeBWorK::CourseEnvironment object to determine which WeBWorK::Authen subclass should be used. $type can be any key given in the %authen hash in the course environment. If the type is not found in the %authen hash, an exception is thrown.
Instantiates a new WeBWorK::Authen object for the given WeBWorK::Controller ($c).
Returns true if verify() returned true the last time it was called.
Future calls to was_verified() will return false, until verify() is called again and succeeds.
