Matrix::multiplyAdd and transposeMultiplyAdd are "level 2" BLAS and speed up the numeric part of the code substantially. Alex might be able to speed them up even more by making them use real BLAS code within Matrix.cpp.

Integrated householder-based QR into NoiseModel. Note that the examples for GFG have changed to ensure that they are actually a linearized version of the nonlinear example.

All std::map<Symbol,T> are now SymbolMap<T>, which is just a thin wrapper around std::map. at(Key) is used instead of first checking with find when an exception should be thrown for non-existent keys. This does not change any behavior or timing currently. This check-in also includes some functions in BayesTree for gathering clique statistics.

changes to append_factor which give more than 2x speedup on my data. Matrices in As are no longer copied/edited/replaced each time they need to be changed, but created once and then updated in place.
