// .NAME vtkQuadratureSchemeDefinition
// .SECTION Description
// An Elemental data type that holds a definition of a
// numerical quadrature scheme. The definition contains
// the requisite information to interpolate to the so called
// quadrature points of the specific scheme. namely:
//
// <pre>
// 1)
// A matrix of shape function weights(shape functions evaluated
// at parametric coordinates of the quadrature points).
//
// 2)
// The number of quadrature points and cell nodes. These parameters
// size the matrix, and allow for convinent evaluation by users
// of the definition.
// </pre>
