Multiple plots of different WS

[Nick Draper]

Alter the user interface to simplify the task of plotting curve from different workspaces on top of each other. Suggestions:

• Allow multiple workspace selection (ensure all of the right click options are valid), then Plot Spectrum (instead of first spectrum) would ask wich spectrun (as long as there was more than one) and plot that spectrum from all workspaces (any that do not contain that index -> error log and no curve).
• As above but when selecting a WS group
• Dragging a WS onto a graph asks which spectrum and adds a curve
• Dragging an index from a matrix WS to an existing plot will add a curve.
• Any other inspirations

[Russell Taylor]

(In [3397]) Add ability to plot spectra other than the first one from the MantidPlot workspace browser. Can also select multiple plots and overlay them. Re #950.

[Martyn Gigg]

(In [3399]) Revert a change that crashes the script interpreter dock. Re #950

[Russell Taylor]

(In [3436]) Fix for an uncaught exception when plotting a spectrum across multiple workspaces, where some workspaces have fewer spectra than the one requested. Re #950.

[Russell Taylor]

(In [3445]) Improve the slickness of plotting simultaneously from multiple workspaces. There's now a plotSpectraList function that takes a list of workspace/index pairs, eliminating the need for a mergePlots. Re #950.

[Russell Taylor]

(In [3446]) Missed some files out of last check-in. Re #950.

[Russell Taylor]

(In [3454]) Add ability to plot spectra by dragging a selection from the workspace browser to an existing graph. Re #950.

[Russell Taylor]

(In [3459]) Add ability to plot (or copy) non-contiguous selection of rows or columns from a Mantid Matrix. Re #950.

[Russell Taylor]

(In [3460]) Ensure graphs update their axes when a new curve is dropped onto them. Re #950.

[Russell Taylor]

(In [3477]) Avoid potential crashes when moving curves in and out of graphs using the CurvesDialog window. Re #950.

[Russell Taylor]

(In [3479]) Prevent plotting of single value workspaces. Re #950.

[Russell Taylor]

(In [3487]) Adjust copying of selected cells between MantidMatrix tabs so that it works for non-contiguous selections. Re #950.

[Russell Taylor]

(In [3502]) The constructor of MantidCurve now throws an exception if the workspace is not in the ADS or if the index given is out of range. Added catches around all the places where a MantidCurve is created. Re #950.

[Russell Taylor]

(In [3505]) Add the ability to add error bars to existing MantidCurves through the Graph->Add Error Bars menu option. Re #950.

[Russell Taylor]

(In [3506]) Improve error reporting and fix a potential crash. Re #950.
