Create a dynamic binned MDEventWorkspace with different coordinate basis

[Michael Reuter]

ConvertToMD is locked into a specific regime of coordinate axes, namely (HKL mode, direct mode) [H,K,L,deltaE,....]. One would ideally like to be able to create a MDEventWorkspace with a coordinate axis set like [H,deltaE,K] and the 4th dimension, L, integrated that takes advantage of the dynamic binning. SliceMD can be used to effect the coordinate change, but it currently returns a "regularized" MDEventWorkspace since it relies on the number of bins for each axis being specified. This isn't really what is desired when creating a new MDEventWorkspace since it the workspace should leverage the dynamic binning capability. Rather than modify the two aforementioned algorithms, a new slicing algorithm should be created to construct a MDEventWorkspace with an arbitrary coordinate axes from a given MDEventWorkspace and that new workspace should be dynamically binned.
