package LProp

    ---Purpose: Handles local properties of curves and surfaces.
    --          Given a curve and a parameter value the following computations
    --          are available :
    --          - point,
    --          - derivatives,
    --          - tangent,
    --          - normal,
    --          - curvature,
    --          - centre of curvature,
    --          - Locals curvature's extremas,
    --          - Points of inflection,
    --          Given a surface and 2 parameters the following computations
    --          are available :
    --          - for each parameter:
    --            - derivatives,
    --            - tangent line,
    --            - centre of curvature,
    --          - point,
    --          - normal line,
    --          - maximum and minimum curvatures,
    --          - principal directions of curvature,
    --          - mean curvature,
    --          - Gaussian curvature.
