Currently the functions mitk::Equal (for geometries) and mitk::IsSubGeometry only offer to pass one eps for the check.
But sometimes (see e.g. MaskUtilities) you want a different eps for the spatial aspects (spacing, origin, ...) or the directions/orientation. Currently it is solved by own boilerplate code.

Introduce a overload versions

bool mitk::Equal(const mitk::BaseGeometry &leftHandSide,
              const mitk::BaseGeometry &rightHandSide,
              ScalarType spatialEps, ScalarType directionalEps,
              bool verbose)

bool mitk::IsSubGeometry(const mitk::BaseGeometry& testGeo,
  const mitk::BaseGeometry& referenceGeo,
  ScalarType spatialEps,
  ScalarType directionalEps,
  bool verbose)

the old versions just call the new one and use their eps for spatial and directional eps.
