// -o- <resolution> is the resolution to set the flags for. Flags are set independently
// for each reosolution.
// -o- <look_ahead> controls whether the look-ahead region is processed. For more information
// on the look-ahead region, please see the reference for the system variables,
// LOOK_AHEAD_PERCENTAGE and LOOK_AHEAD_DISTANCE.
// -o- <thick> controls the operation of the minimum thickness checker. If this is turned
// off, any 'spike' will be considered a feature, regardless of thickness. For more
// information, please see the system variable reference for MIN_FEATURE_THICKNESS and
// MIN_SPIKE_THICKNESS.
// -o- <refinetop> controls top refinement for the feature. Note that the current refine_top
// algorithm contains only a simple check to make sure that no points above the current
// feature top exceed the threshold.
// -o- <refinebase> controls the base refinement for the feature.
// -o- <gap> controls the gap 'stitching' algorithm. When on, this sub-functor joins spatially
// close features into a single feature using values stored in the system variable
// MAX_GAP_DISTANCE.
