ENH: Add box kernel to morphological operations apps

Merged Laurențiu Nicola requested to merge app-binary-morhological-oper into develop

Summary

  • remove some code duplication in appBinaryMorphologicalOperations and appGrayScaleMorphologicalOperation
  • add support for box structuring elements to the above
  • rename structype.foo.{x,y}radius parameters to {x,y}radius

Rationale

Box kernels are very common, and they're easy to add they are already available in ITK.

Implementation Details

The refactoring was necessary to avoid having N_kernels * N_filters cases (now it's N_kernels + N_filters instead).

The radii are used by all supported kernels, so they're now unrelated parameters; this avoids some more code duplication.

Additional notes

If we ever want to support image kernels, the radii parameters will make no sense. A warning can be added in that case.
