								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.

								Bugfix in Rot3::logmap.  The function checked for a trace of 3, but the check could fail due to rounding errors, causing the function to try to take acos(something larger than 1) resulting in NaNs being returned.

								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.

								Added a 1D manifold implementation of 2D rotations. The new representation stores (cos theta, sin theta) rather than theta itself, ensuring that (a) rotate and unrotate do not call cos/sin, (b) same for all derivatives of rotate and unrotate, (c) when you call angle(), you always get the standardized answer given by atan2. The idea is that we will use this new type in Pose2 instead of angle.

- similarly, moved implementations after constructors in .cpp file
- removed obsolete assert_equal
