    @brief Intersect a shape or shapes with a RecordGroup

    @ingroup shape

    The configured criteria should be either a Record or RecordGroup of shapes.
    Each criteria Record is checked to contain a "bnd:shape" attribute or to be
    a shape itself.

    Currently, the supported shapes are sphere and cylinder.

    As a SelectorI, "marking" a shape is defined as setting any
    "bnd:picked" atrribute to 1.
