    RiSplineAPI is a general purpose API schema used to describe
    a named spline stored as a set of attributes on a prim.
    
    It is an add-on schema that can be applied many times to a prim with
    different spline names. All the attributes authored by the schema
    are namespaced under "$NAME:spline:", with the name of the
    spline providing a namespace for the attributes.

    The spline describes a 2D piecewise cubic curve with a position and
    value for each knot. This is chosen to give straightforward artistic
    control over the shape. The supported basis types are:

    - linear (UsdRiTokens->linear)
    - bspline (UsdRiTokens->bspline)
    - Catmull-Rom (UsdRiTokens->catmullRom)
