<B>Description:</B>
    This checker the degree of polynomial curve.
    The degree of the polynomial depiction for a curve segment determines the number of degrees
    of freedom (variance) of a curve. The higher the degree, the greater the complexity of the
    curve. Curves with high polynomial degrees are susceptible for unintentional or unwanted
    definition and curvature and therefore, where appropriate, must be approximated when
    translated to another CAD, CAM, or CAE system, i.e., approximated within the bounds of the
    given accuracy. In both cases, this generally means a worsening of data quality.
    Recommendation: High-degree polynomial curves should be avoided. High-degree polynomial curves
    may be subdivided into curves of smaller degree with respect to the given accuracy.
