Datatype for parameters of the FPT used for 1d, 2d and 3d.
Stores of the parameters for a fast conversion of a modal Legendre expansion to point values (located at Chebyshev nodes) and vice versa. \n The FPT covers: \n - Transformation from Legendre expansion to point values at Chebyshev nodes \n - Transformation from point values (Chebyshev nodes) to modal Legendre expansion \n
