Builds quadratic polynomials coefficients from cell mean and edge values.

Parameters:

n	Number of cells
h	Cell widths
u	Cell averages
ppoly_e	Edge values, with the same units as u.
ppoly_coef	Polynomial coefficients, mainly with the same units as u.
h_neglect	A negligibly small width in the same units as h.

    )

Reconstruction by parabolas within boundary cells.

Parameters:

n	Number of cells
h	cell widths (size N)
u	cell averages (size N)
ppoly_e	edge values of piecewise polynomials, with the same units as u.
ppoly_coef	coefficients of piecewise polynomials, mainly with the same units as u.
h_neglect	A negligibly small width for the purpose of cell reconstructions in the same units as h.
