Development:Userenrols plugin

This course import plugin allows you to import user enrollments from an uploaded delimited text file. New user accounts will not be created, so each of the users listed in the input file must already have an account set up in the site. The course role into which new enrollments are made is selectable. Optionally, you also can assign imported users to course groups as part of the same import process.

This plugin is a refactor of the mass_enroll course admin mod done by Patrick Pollet and Valery Fremaux, using the existing groups import plugin (Jamie Pratt & Tim Hunt ?) as a template.
