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.

demeaning, or scaling to percent-changed. Added ability to plot data
reduced against a PE/COPE, and the ability to hide the raw data plot for
a currently-selected FEAT time series (as the plot can get pretty messy).

being shown. Other little changes.

method). This is really just for the 'current' time series, so that e.g.
FEAT settings will persist with location changes. On the topic of FEAT
settings, when the selected overlay is a FEATImage, a new settings group
appears in the TSControlPanel allowing the user to change FEAT settings
for the 'current' TS plot. Non-functional currently, but the GUI is
there.

stuff. Overlay load function auto-detects FEAT-like images and creates
FEATImage instances instead of Image instances where necessary.

HistogramListPanel (if it exists) via a slightly convoluted process
involving the 'HistogramPanel.selectedSeries' property.

subclasses manage their properties separately. New property on
HistogramPanel - selectedSeries - which will be used to link the
HistogramListPanel with the HistogramControlPanel without them
explicitly knowing about each other.

creating RGB array - this allows us to save as PDF/SVG/etc/etc.

its functionlaity is used, but it is not displayed. Log plots are now
done using matplotlib scale='log'. Ticks are now automatically generated
by matplotlib instead of being manually generated by me.

initial histogram calculation.

avoid having to perform the initial data range/histogram calculation

in end-bins of histogram. Tweaks to histogram data to make it look
better (i.e. plot ends finish at y=0.0). PlotPanel.drawDataSeries
accepts arbitrary **kwargs which are passed through to the plt.plot
function (and used by the HistogramPanel to draw histograms as step
plots).
