SequentialDifferentialVariable(S)

OrderlyDifferentialVariable adds a commonly used sequential ranking to the set of derivatives of an ordered list of differential indeterminates. A sequential ranking is a ranking < of the derivatives with the property that for any derivative v, there are only a finite number of derivatives u with u < v. This domain belongs to DifferentialVariableCategory. It defines weight to be just order, and it defines a sequential ranking < on derivatives u by the lexicographic order on the pair (variable(u), order(u)).
