The output produced by a software tool is compared to the reference results provided with each test case. The comparison is done per-column, number-by-number. The evaluation consists of testing the data value for each variable at each time step, and comparing the values according to the following formula:
- need to deal w case that a tool may not output a given species
- need to figure out what to do about discontinuities; see
- what to do to test Constraint?
