Kasper Sørensen reassigned METAMODEL-61:
----------------------------------------

    Assignee: Ashwin Rayaprolu  (was: Kasper Sørensen)

Alright you're assigned.

A small hint/idea on implementation: A lot of MetaModel users already rely on CsvDataContext
and it is also a pretty non-trivial class by now. So rather than enriching this class maybe
it's wiser to create a new class "CsvDirectoryDataContext" or so, but composing functionality
of the existing one. This new class could easily delegate to CsvDataContext for all the per-table
operations.

> Right now the CsvDataContext supports reading just a single file and having that as a
single table. It would be wonderful if you could also instantiate CsvDataContext (or some
other class) with a folder instead of a file, and then have every csv file in the folder show
up as a table in the schema. That would allow CsvDataContext (or whatever it will be) to be
used as a functional replacement for almost any other UpdateableDataContext, e.g. for testing
etc.
