Turn regulation evaluation into a selection for a space object
regularity_eval_to_selection(reg_eval_res)Returns an object with either the point-matrix or the hyperslab-selection array. The resulting object is
of class point_selection or hyperslab_selection.
The result of the args_regularity_evaluation function
Holger Hoefling
Analyzes the results of the regularity evaluation of each dimension and checks if
it needs to be into a hyperslab-selection or a point-selection. A hyperslab selection will be chosen
whenever there are significantly less of it than the number of selected points. The ratio is determined
by the option hdf5r.point_to_hyperslab_ratio. If this is 1, then always hyperslabs will be used.
