This class contains a grid, the same size as the image, filled in with
PCA (Principal Component Analysis, formerly known as Quadric) data for
each pixel that passed the first and zeroth moment tests.
given the image coordinates in x,y form, returns the screen
coordinates of the cooresponding point
NOTE: point (0,0) is the top left most pixel on the actual screen, so
(x.5, y.5) is in the center of the pixel (x,y)
Provides the user with a means of changing parameters defined in
the SvpParameters class on the fly
TODO: create an easy method for adding new fields to the ParamEditor
which can be called in the constructor for each field.
This class is responsible for storing groups of PCA objects (QuadricFits)
and determining if other QuadicFits are good candidates to add to
the group based on their theta and width.
given the screen coordinates in x,y form, returns the image
coordinates of the cooresponding point (in x,y form)
NOTE: point (0,0) is the top left most pixel on the actual screen, so
(x.5, y.5) is in the center of the pixel (x,y)
