Avoid creating matrix for color fill plots of workspaces

[Martyn Gigg]

Creating a colour fill plot from a workspace currently requires a MantidMatrix to be created first.

We have already successfully avoided this for the spectrum plots and the SliceViewer has a custom QwtRasterData source that understands workspace sources. We should use the same source or share as much code as possible with the QwtRasterDataMD.

[Martyn Gigg]

Move QwtRasterDataMD to QtAPI so it can be reused elsewhere.

Use Axis::indexOfValue methods in MatrixWorkspace.

Removes the requirement for ugly casts. It also fixes a bug with looking up the index from a spectrum axis where it was assuming that the spectrum number mapped directly to the index. This fixes the SliceViewer so that it now displays ragged workspaces correctly. Refs #9319

A couple of performance tweaks for graphing in general.

Graph::updateScale was calling replot then QwtPlotZoomer::setZoomBase, which also calls replot so we turn of the replot in setZoomBase. The ScaleEngine was creating the helper classes on the heap for no good reason so removing that removes many calls to new/delete. Refs #9319

Be smarter about finding the index from a value on a SpectraAxis

We know that the values tend to be quite close so start searching close to the given value and then loop over everything if necessary. Refs #9319

Branch: feature/9319_no_table_colorfill_plots

Tester: This will require a 2D workspace to test. A good example is one of the direct geometry reduced files in the system tests reference directory, e.g. MARIReduction.nxs. Load the file and check that creating a colorfill plot works and does not create an intermediate matrix anymore. Check that

• deleting the workspace closes the plot
• replacing the workspace updates the contents of the plot
• type mtd.clear() in the ipython console and the plot should close

A new command, plot2D has been introduced for plotting from python. It is described here: http://www.mantidproject.org/MantidPlot:_Image_and_Contour_Line_Plots_(Spectrograms), in the section Creating Colour Map or Contour Plots from Workspaces. Try out the commands and make sure they work as intended.

I opened Mantid 3.2 to verify the issues prior to testing. I built the branch locally to verify the changes made address the issues noted in comment:25 & the description, which they do.

I ran the new commands added to the wiki and the Customisation section to verify they work as intended. They do.

No issues with build servers. Code changes and tests written are good.
