The "angle" variable was not being initialized in any of the
constructors for the CutDimensionSet, and nothing was being initialized
by the default constructor. This commit adds angle as an optional final
argument to the parameterized constructors, defaulting to 0.0, and adds
default values to the default constructor using the first of each enum
and 0.0 for the angle. The default constructor is required elsewhere in
the code so cannot be trivially removed. Issue identified by Coverity.
