Detailed Description

NODE2d holds graph nodes corresponding to frames, for use in sparse bundle adjustment type double must be <double> or <float>

Each node has a 6DOF pose, encoded as a translation vector and rotation unit quaternion (Eigen classes). These represent the pose of the node in the world frame.

The pose generates a 3x4 homogenous transform, taking a point in world coordinates into the node coordinates.

Additionally a 3x4 homogenous transform is composed from the pose transform and a projection transform to the frame image coordinates.

Projections from points to features are in a list. There should also be a reverse index from features to projections and points, so that matched features can tie in to points.
