tests should have a timer test.

[Telpe]

To have a test return false if too slow, first we must run a method that take the limit time.
because computers performe differently, we can not establish the time limit from any other computer than the one that runs the actual tests.

if not a timed test, then if multiple solutions, print time and delta time for them.

if 1 solution, just time it. perhaps compare to similar functions.
