/**
 * @class   vtkmThreshold
 * @brief   extracts cells where scalar value in cell satisfies threshold criterion
 *
 * vtkmThreshold is a filter that extracts cells from any dataset type that
 * satisfy a threshold criterion. A cell satisfies the criterion if the
 * scalar value of every point or cell satisfies the criterion. The
 * criterion takes the form of between two values. The output of this
 * filter is an unstructured grid.
 *
 * Note that scalar values are available from the point and cell attribute
 * data. By default, point data is used to obtain scalars, but you can
 * control this behavior. See the AttributeMode ivar below.
