sorted eigenvalues. I do not understand numpy indexing.

dtifit.py. Added new function, decomposeTensorMatrix, which turns a 6
volume tensor matrix image into eigenvalue and eigenvector images.

readbuf size, despite profiling showing that it doesn't make much
difference.

when both q/sforms are unknown. Otherwise should default to
nibabel. Also added method to MelodicClassification to return all labels.

instead of props.

passed through to listener functions.

a warning if the sub-class is also a HasProperties, because both classes
define a 'notify' method, which could be super confusing.

anymore, and might get deleted.

of lenght 1.

instanceified. Image.isNeurological is now memoized.

keyword arguments.

TaskThread also doesn't crash when an enqueued task raises an error.

'intent' attribute.

a new thread.

2. ImageWrapper marks its expand coverage task thread as a daemon.

because __taskThread attr does not exist.

optionally be told to calculate data ranges on a separate thread.

to collapse many little expansions (that cover individual volumes) into
a few larger ones (that cover many volumes).

equivalent expansions which pertain to adjacent vectors/slices/volumes.

Bugfix in ImageWrapper.calcExpansion - could not handle slice outside of
coverage, but overlapping with some dimensions.

Initial support in Image class for data editing.

regions are specified with nan (which can't be represented as uint32).
