2. Updated documentation references to __init__ methods, as sphinx
   doesn't resolve them.

3. Bug fix in featresults module when loading contrast matrix.

useful to more than just the location panel.

displayed with the bottom left voxel at display location (0, 0). This
means that calculating voxel location from display coordinates is
different depending on the space that the image is displayed in. I think
I've figured out the location panel, but need to double check, and need
to take a closer look at the editor.

NaNs. TimeSeriesPanel uses the same (random) colour for unselected
overlays. It's a bit dodgy, I will refactor it some time in the future.

ActionProvider instances are now SyncableHasProps instances, and
DisplayOpts instances are now ActionProvider instances. A few
tweaks to __init__ calls throughout the affected class hierarchy.

minor fixes.

DisplayOpts instances. ModelOpts is correspondingly broken, but about to
be fixed.

invert (and replaced the previously-incorrect inverted scale->contrast
equation). VolumeOpts was incorrectly flipping the resulting bricon
values, as well.

Other small changes - fsldirdlg layout tweak, and ActionButton now does
not require the action to be listed in the strings module.

be more instances of this that will crop up.

the props package.

ClusterPanel when display z stats. Not implemented in GL14 yet. New
random lut that should have been in previous commit.

views can now display different volumes of the same 4D image - nice!
GLVolume listens for sync changes on vol/res/etc properties - if
unsynced, a new, independent image texture is created. When synced back,
the independent texture is destroyed, and the original one re-acquired.
Need to update other GL types to do the same.

can be de-registered

but at the cost of not being able to disconnect them across different
views. Hopefully will fix this in the future.
