Added a new combine process for GaussianFactors that allocates only one matrix when combining, rather than using append factor to make a large number of smaller matrices. There is a flag to switch between these modes, which currently defaults to the older approach. Currently, there does not appear to be a performance improvement, however.

multiplyInPlace shaves a few seconds off but is fairly dangerous - I feel ambivalent....

add linear system as a template parameter in nonlinear optimizer
...
fixed a nasty bug and change the internal data type of subgraph preconditioner from reference to boost shared pointer. reference is not a good idea for class members, because no type checking will happen

Refactoring to use a new Symbol key instead of strings in Bayes*, Gaussian*, Ordering, Symbolic*, VectorConfig. Renamed existing type-checking key Symbol<C,T> to TypedSymbol<C,T>

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.
