Done.

Feel free to tackle those.
Maybe the "ContinuedFraction" class should be included in
the "fraction" module (rather then have one of its own).

There are several in Commons Math. Shall we port only the more
robust and efficient ones (e.g. drop "RegulaFalsi")?

In "core" or in a module of its own?

Some array utilities are definitely needed (i.e. scalar and cross
products, linear combination). [Some unit tests of "QuaternionTest"
use "Vector3D", which is out of scope.].

Is module "core" the right place for "MathArrays"?
Is the name OK?

Thanks Gilles, I think I have all the necessary git manipulations worked
out, I will see if I can create a "fraction" module.
