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.

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.

Changed the interface on Matrix::column() so that it uses the one in our library (now called column_() ) rather than the boost default. Currently, our implementation just uses the boost default, but this may change due to timing results.

Checked Matrix::collect() with different timing metric, and memcpy has approx 25% speedup over original version. Matrix_range is slower or the same speed as the original version.

Implemented a version of collect() using matrix_range, but it had worse performance than memcpy. New version of vector_scale[column] with new pointer arithmetic implementation for approx 20% improvement.
