WeBWorK::Authen::Cosign - Authentication plug in for cosign
to use: include in localOverrides.conf or course.conf $authen{user_module} = "WeBWorK::Authen::Cosign"; and add /webwork2 or /webwork2/courseName as a CosignProtected Location
if $c->ce->{cosignoff} is set for a course, authentication reverts to standard WeBWorK authentication.
