Details:

In the source code file "regionprops.m" of the release image-2.2.2 the
properties "orientation", "majoraxislength" and "minoraxislength" are included
but commented out (and not listed in the all_props list at the beginning of
the file). I found their output reasonable and useful, would it be possible to
comment them in for the next release of the image package?

Additionally the property "eccentricity" could be easily implemented: with
a=majoraxislength and b=minoraxislength it is definded as
eccentricity=sqrt(1-(b/a)^2) .
