Metadata

Rachel's Comments

1) Can we get implement convenience methods to get metadata? I've found
that maintaining a set of commands to get one piece of information is
really difficult – developers don't like to see sequences like that.

Extracted from Design Document

Having pushed metadata out into a separate service it probably makes sense to bring Grading information back into the offering and section objects. This needs further work.

It may also be useful to define significant events associated with a section, such as mid-terms, finals, project due dates, etc. This could be included in the Schedule object, or included as metadata. TBD
