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.

Deriving Lie objects from a base class Lie<T>, which provides member functions to access global functions, for use in MATLAB.

Large refactoring - made several Lie group functions global, which used to be member functions, to treat Lie groups more uniformly. Also created Lie.h, and a preprocessor flag in numericalDerivative to change the coordinate frame derivatives are reported in. gtsam and easylib build and pass unit tests, but this will probably break other projects, which will require a few small changes to work again. Email coming in a few minutes to describe the changes.

Made 'between' derivatives in the tangent space of the solution instead of tangent space of identity, this makes Pose2 an "origin-free" manifold.

Closing # 118: Made Pose2 use Rot2, added 'compose' for Pose2, made slight modifications to Rot2. Also added additional unit tests. This change shouldn't break anything but let me know if it does.

made all classes that currently have an assert_equal "Testable"
...
- derive from testable as in class Point2 : Testable<Point2>
- moved print and equal declarations in .h right after the constructor
- similarly, moved implementations after constructors in .cpp file
- removed obsolete assert_equal
