GhostCorrection algorithm for EventWorkspaces

Description
The algorithm will take an EventWorkspace and calculate a ghost-correction histogram. It will create a new Workspace2D with the ghost correction to apply to the data.
Input Parameters:
- Original event workspace file (can be either in d-spacing units or TOF)
- Grouping/aligning .cal file (for aligning and/or DiffractionFocussing)
- Ghost Correction file (binary format file with 16 structs for each pixel)
- Rebinning parameters
- Output Workspace2D name.
- Perhaps an option to also histogram the incoming data and make another WS2D with the corrected data?
See the HistoTools SVN code for some code that does some of this.

Still missing the second-order correction (if it is needed) but this algorithm seems to run and give reasonable results as is. Closing the ticket for this iteration; make a new one for the 2nd order correction if needed.

This works correctly.
