Stream Track

The TrackStream class is the main class for creating a StreamTrack given data. The TrackStream will fit the track to the data, in Sci-Kit Learn style with methods “fit”, “predict”, and “fit-predict”.

The StreamTrack is analogous to an interpolated CoordinateFrame where the data is is a univariate function of the track arc-length. The call method returns a BaseCoordinateFrame by evaluating the interpolations.
