Preprocessor SortWordString, sorts the indivual strings in ascending order.
This is useful in conjunction with the CCommWordStringKernel and will result in the spectrum kernel. For this to work the strings have to be mapped into a binary higher order representation first (cf. obtain_from_*() functions in CStringFeatures)
