Detailed Description

template<typename KEY, typename VALUE>
class gtsam::FastMap< KEY, VALUE >

FastMap is a thin wrapper around std::map that uses the boost fast_pool_allocator instead of the default STL allocator. This is just a convenience to avoid having lengthy types in the code. Through timing, we've seen that the fast_pool_allocator can lead to speedups of several percent.
