Numerical integration method enum

Note on computations

For the considered integral to be consistent across compute methods for a given description, the left-rectangle (resp. right-rectangle) has to ignore the last (resp. first) value given in the descriptors. This can be visualized in the following example:

Out of 11 samples, both methods compute the area of 10 polygons. In the case where the domain is uniform & described using a step, the eleventh sample value is useless (for a left-rectangle method).

The crate assumes that the first and last samples making up your domain corresponds to the limits of the integral. Therefore, these values will be ignored when computing the integral using rectangles.
