ECP Updates

[MS-19/04] Ghost Cells
- Dave added a filter that removes ghost cells
- Just made a filter that adds a ghost layer array to structured grids (to mark external areas as ghost).
- It was suggested that for completion of the milestone, the histogram filter should be modified to optionally accept a ghost cell array to ignore inputs from ghost cells.
- Ken and Rob need to talk a look at merge request
[MS-19/05] Merge Points
- Ken is on the hook for merging the Merge Points worklet in.
- Ken spent some time implementing this.
