reconstruct()

Calculate a 1D PLM reconstructions based on h(:) and u(:)

Detailed Description

This implementation of PLM follows Colella and Woodward, 1984, except for assuming uniform cell thicknesses. Cells resort to PCM for extrema including first and last cells in column. The cell-wise reconstructions are limited so that the edge values (which are also the extrema in a cell) are bounded by the neighbor cell means. However, this does not yield monotonic profiles for the whole column.

Note that internally the edge values, rather than the PLM slope, are stored to ensure resulting calculations are properly bounded.
