BetweenFactor is a template that models the measurement between two Lie types e.g. Pose2 or Pose3. Pose2Factor and Pose3Factor are now simply typedefs.

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.

Small change necessitating lots of edits: Conditionals now include key of random variable
...
This simplifies Bayes nets quite a bit. Also created a Conditional base class, derived classes ConditionalGaussian and SymbolicConditional

BIG CHANGE: I got rid of the BayesChain/ChordalBayesNet classes and we now simply have a BayesNet class. It will just happen to be chordal when it is the result of an elimination. This will simplify a lot of things.
...
The main renaming that happened is
BayesChain -> BayesNet
ChordalBayesNet -> GaussianBayesNet == BayesNet<ConditionalGaussian>
SymbolicBayesChain -> SymbolicBayesNet == BayesNet<SymbolicConditional>

Removed ConstrainedChordalBayesNet and associated test. It may return if ConstrainedConditionalGaussians need more involved processing in future versions, but for all versions of LinearConstraint, there is no need for a special Constrained CBN.

'''BIG CHANGE''': avoid converting back and to FGConfigs by templating on configuration type. Details:
...
* Factors are now templated on the configuration type. Factor Graphs are now templated on the factor type and configuration type.
* LinearFactor is a factor on an FGConfig.
* LinearFactorGraph uses LinearFactor and FGConfig.
* NonLinearFactor is still templated on Config.
* NonLinearFactorGraph uses NonLinearFactors, but is still templated on Config.
* Tests and VSLAMFactor have been updated to reflect those changes.

2 BIG changes:
...
(1) FactorGraph and NonlinearOptimizer now no longer have a .cpp file, but a -inl.h file as in [http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml Google's C++ Style Guide]. This means if you expect to instantiate one of the functions in a cpp file, you have to include the -inl.h file.
(1) getOrdering is now in FactorGraph, and the non-linear version does *not* take a config anymore.
Long version: I made this change because colamd works on the graph structure alone, and should not depend on the type of graph. Instead, because getOrdering happened to implemented in LinearFactorGraph first, the non-linear version converted to a linear factor graph (at the cost of an unnecessary linearization), and then threw all that away to call colamd. To implement this in a key-neutral way (a hidden agenda), i had to modify the keys_ type to a list, so a lot of changes resulted from that.

BIG: replaced optimize in NonlinearFactorGraph with specialized NonlinearOptimizer object. This does away with the artificial ErrorVectorConfig and the like as NonlinearOptimizer is templated and can use "exmap", the exponential map defined for any differentiable manifold.
