Description

Introduce a unit tests for optimizers.

Currently, this only test for the FIRE algorithm, using the Rozenbrock test function. More functions could be added, as well as more unit tests.

This should be used to validate changes to the optimizers.

Here is the plot of the output of the unit test, from the results of the optimization.log file.
