Introduction of new tests for the plotting options, covering:
Errors selected
Axis limits changed in options
Axis limits changed through the figure toolbar
Autoscale requested

Due to the addition of the plotting options the tests were failing.

Previously the options were reset when a new run was loaded, or a plotting option was changed e.g to tiled plotting. To make this change the default axis limits are now only used if no limits are present in the quickEdit axis bounds boxes.

Adding plotting options to the dock widget. This is added through the quickEdit_widget used in elemental analysis.

This commit adds the widget, and tests the error checkbox
Implementing plotting options

Commented out code has been removed
Cleaning up and removing unnecessary comments
Pairing and grouping tables column numbers and now defined at the top of the file.

If the plotting was tiled the plot_standard_workspaces would not remove previous workspaces, such as those from a rebin.

Generating appropriate legend labels for frequency domain analysis by adding a new clause into the 

The plotting kwargs has been moved into the presenter, to enable it to be changed based on view controls. Continuing to rewrite tests
Adding tests to cover the tiled plotting
Additional plot widget_model tests
Adding unit tests for plotting_widget

Plots now update if workspace is replaced or deleted.
Can now analyse pairs and groups concurrently

The multi-period widget was removed from the GUI when the home grouping widget was removed. This has now been added back in.

Based on the feedback from a scientist the home tab group widget is being removed.
Plotting is now controlled in the grouping tab

The tables in the grouping table now have analyse column, which decides whether the group or pair will be plotted.
Adding option 'tiled by'

This enables the plots to be tiled by run or group/pair

Plot will now auto update its layout on resize

Fitting tab is updated to abide by the groups and pairs selected in the grouping tab

Tiled plotting scales to the same axis

Separating dock widget into its own file such that the window layout will update when the window is docked and undocked

Updating plots if the rebin options are changed

Clearing up the plot window if the underlying workspaces are deleted.

Formatting and removal of print statement

Cleaning up code comments. Changing the plot guess logic so it remains enabled when a new run is loaded.

Cleaning up the call to plot, such that it no longer takes a redraw option. This was chosen to simplify the logic, as the same plotting window is used throughout.

Adjusting the unit tests such that they test the new combined plotting widget.

The dockable plot widget is now contained within a new widget. Which has been created based on the HomePlotWidget MVP model.

The observer pattern is not Muon specific and could be used elsewhere. Moving it to somewhere not related to the muon GUI reduces the chance of the code being duplicated.
