Holds the results of an approximation of the PP-estimators for sparse and robust PCA using the grid search algorithm in the plane.

Objects can be created by calls of the form `new("SPcaGrid", ...)`

but the
usual way of creating `SPcaGrid`

objects is a call to the function
`SPcaGrid()`

which serves as a constructor.
