- the StaticTabulated2DFunction class and the base class
(Tabulated2DFunction) are gone
- the DynamicTabulated2DFunction class has been renamed to
UniformTabulated2DFunction
- a new class called UniformXTabulated2DFunction has been
introduced. Like UniformTabulated2DFunction, it assumes uniform
intervalls of the sampling points in X direction, but in contrast to
UniformTabulated2DFunction, the Y locations of the sampling points
can be set freely (as long as they are specified in increasing order
for each x value)
- add a unit test for the two tabulation classes
