Arithmetic and mathematical operations with objects of Transition* classes
Standard arithmetic operators for computations with
Transition* objects and numeric values.
Transition objects must have the same extent and resolution.
All arithmetic and mathematical operations that work on the sparse matrices are available for
Transition* object or numeric.
