GrainMap class

[jadball]

We need a class to store information about a spatial map of a grain/multiple grains.
This class should do at least the following:

• I/O to HDF5 group
• Calculation of the following arrays:
  • Grain ID - by combining recons from multiple different grains together
  • Per-grain UBI - from grain objects
  • Per-voxel UBI - by local refinement
  • IPF X, Y, Z
  • Misorientation
  • Grain ID (segmentation from point-by-point data?)
  • Phase ID?
• Creation methods:
  • From a list of GrainSinogram objects
  • Form the UBI array directly from point-by-point indexing

Mostly completed by #322 - per-voxel UBI by local refinement is ongoing, and I'm not sure we should be segmenting point-by-point data (leave as a task for MTEX?)

[jonwright]

About MTEX - the main problem seems to be output of multi-channel versus single channel results. Does MTEX allow several orientations per point together with a weight for each one?

[jadball]

No, as far as I am aware MTEX is single-valued. I have implemented a MTEX CTF export as a TensorMap classmethod.
