-The 4th and 3rd grade equation solvers: Need to try JDebord's lib

As far as I can see, his routines are similar to my RootPolX (X = degree of equation) functions. The execution times would be similar, too...

On the other hand, you could try my RootPol function, which uses a different algorithm (eigenvalues of companion matrix). I have not checked its execution time, though...
