Improve usability of fitting e.g. during calibration

[Martyn Gigg]

Usability of fitting e.g. during calibration:

• Single peak - Initial guesses based on instrument in non-TOF units (all)
• Improved algorithms for different dspacing range, e.g. different shapes for different banks
• Look at things done on e.g. SXD
• Defined outputs based on instrument/technique
• Batch fitting with functions, consider interface to GSAS (Pascal)

Ask Pascal Manuel for more information.

Batch modify all SSC tickets to critical priority (this will also show up as an update for all those already as critical)
