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.
