support multiview CT

[maxthemouse]

Need a script to handle the output of the multiview CT program. CT done with the multiview program results in a single long sequence of images with all flats, darks and projections of each view. It would be good to have a script to rename and organize the files.

• The first step will be just to rename and move into new folders. This allows people to use any software for processing.
• The second step will be to to do the flat-correction processing. This would likely be done at the same time as step one to avoid the overhead of reading and writing each file twice.
• The third step will be to add reconstruction or other desired features. These things should be done one at a time. It may better to open new issues for each of these and refer back to this issue.
