Create a MDEventWorkspace

Blocking: #2012 Tester: Roman Tolchenov

Description

  • Necessary for completing #2012.
  • Create a data format that saves neutron event data after converting from instrument space (event at TOF x on pixel y) to a reciprocal space representation (Qx, Qy, Qz, (possibly)E, (possibly)other dimensions).
  • Events will have weights and errors, as in the case of EventWorkspace.
    • Unlike EventWorkspace, there will not be a non-weighted option. We can assume that there will always have been some kind of correction requiring weights.
  • Needs to handle large number of points: 1G to 100G.
    • Keep as much as possible in memory, spawn to disk as needed.
  • Sparse representation.
  • Should be possible to distribute the computing, at least to parallel threads on one machine and maybe later to several machines.
