put Factorization class in its own file, and added checks in constructors that take shared pointers, so we get some more meaningful output rather than *segmentation error*

Rot2 "named constructors" ( http://www.parashift.com/c++-faq-lite/ctors.html#faq-10.8 ):
...
/** Named constructor from angle == exponential map at identity */
static Rot2 fromAngle(double theta) { return Rot2(cos(theta),sin(theta));}
/** Named constructor from cos(theta),sin(theta) pair, will *not* normalize! */
static Rot2 fromCosSin(double c, double s);
/** Named constructor that behaves as atan2, i.e., y,x order (!) and normalizes */
static Rot2 atan2(double y, double x);
which are a bit more verbose, but at least won't cause hours of bug-tracking :-(
I also made most compose, inverse, and rotate functions into methods, with the global functions mostly calling the methods. Methods have privileged access to members and hence are typically much more readable.

Baker–Campbell–Hausdorff formula: in non-commutative Lie groups, when composing exp(Z) = exp(X)exp(Y) it is not true that Z = X+Y. Instead, Z can be calculated using the BCH formula:
...
Z = X + Y + [X,Y]/2 + [X-Y,[X,Y]]/12 - [Y,[X,[X,Y]]]/24 + ...
