<B>Description:</B>
    This checker complies PDQ criterion Tiny Edge (G-ED-TI), which searches
    for all selected tiny edges for which the arc length of the edge or segments
    is less than the specified distance tolerance.
    Edge curves that fall short of a particular length may lead to invalid
    elements, especially during the exchange of data (in a system with reduced
    precision). Because of this, the definition of bounded surfaces, as well as
    the correct topology information, may get lost so that only the untrimmed
    surface will be transferred.
    Recommendation: Consolidate the edge curves with bordering edge curves for
    a new bounded surface, or delete/enlarge the tiny edge curves and rectify
    the connecting elements appropriately.
