We need to be able to push issues back up to the caller.

Getting things under tests reveals that we really don't want to be touching real files as part of our new transfer strategy test. I'm therefore refactoring things to use a MeasurementSource (read Repository pattern) so that I can mock out the geneartion of Measurement(s) (new type) such that I can purely test the Transfer logic in this TransferStrategy.

Location will be required to complete the transfer for some stategies. Also, filtering on each transfer may need the full file name, not just the stripped out run number, so lets move that to the model.

The catalog searcher used to pre-filter out anything but raw files. This is a problem because our filtering depends on the transfer strategy. Instead. We defer the filtering util the model is displayed, and we use the TransferStrategy to tell us which files we can use in our transfer list.

Interupt to handle UI events as part of the reporting increments. Progress viewing (in the UI) and progress notification (in the working parts of the code) are now synched via the ReflProgress type.

Really important that transfering has an associated progress. The measure based approache will take some time to complete.

Increase test coverage. Add performance tests, and refactor the implementation a little.

but users might use it too. Wanted to make a separate ticket for this but trac is down

Refs #3724: Pulled wiki description text from the wiki site and added in algorithms' header file with special tags. The auto_wiki.py script can retrieve the text to generate the wiki page fully.

Refs #3507. Full-move to MVP. Sorry for large checkin, but these things are all dependent and cannot have partially working GUI code.

Refs #3157 Sort our System.h. It was becoming a dumping ground. It should only be touched when absolutely necessary as it affects every file in Mantid. Also combined this with Refs #2345 to sort out DLLExport/DLLImport usage. It's done for Kernel, Geometry and API but stuff in the plugins could do with updating as well.
