melodicanalysis functions - .gica suffix no longer recognised.

returning/assuming transposed affines (column-major). This is because that's
what OpenGL uses.

scaling on partial model fits. Also added new method
isFirstLevelAnalysis.

ordered dict.

fsl.utils.path. Featresults get*File functions use addExt instead of
glob, as it is much more robust.

having everything floating point would be a problem. Also fixed little
bug in FeatTimeSeries - overlay was being set to None.

cluster panel was trying to load ztats for contrast -1 when no cluster
results.

module. Hopefully fixed TimeSeries confusion w.r.t. nested
.feat/.ica directories

directory given a path, and to get top level analysis directory.

hopefully less buggy.

controlled by the usePixdim and plotMode properties are now performed
by the TimeSeriesPanel, instead of the TimeSeries class. This was done
because TimeSeries instances added to the list already had
scaling/offsetting applied, so it was potentially being doubly applied.
This is no longer the case, due to a new 'preproc' option in the
PlotPanel.drawDataSeries method.

Also added some melodic specific stuff to the OverlayInfoPanel.

Also fixed the overlay.guessDataSourceType to handle melodic analyses
that are located inside other melodic/feat analysis directories.

Also tweaked the new colourmaps.randomDarkColour function to be slightly
less dark.

and stubs so far.

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

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

featresults loadClusterResults function transforms them into
voxels. Max movie mode rate changed to 1 second.

coordinates are in standard space, rather than voxels. Fixed the former,
but not the latter.

for cluster masks (and other random label images).

add Z statistics and cluster masks as overlays.

op.split.

clustering has been run or not, as design.fsf settings are very
fickle. Instead, I am using the existence of cluster_*txt to determine
whether or not they exist.

DisplayContext.getDisplay was potentially creating Display/Opts
instances for overlays that were not in overlay list. This has been
rectified.

now in a module called featresults.py, which allows query/load of
settings, files, etc.

Also added ability to load an overlay from a FEAT directory (instead of
having to specify the filtered_func_data). But WX does not have a file
dialog which allows selection of either files or directories, so this
new feature can only be done via command line at present.
