NO_EMPTY_CELL

#define NO_EMPTY_CELL

Don't use the empty cell.

This symbol must be defined in order to suppress the usage of the empty cell (of dimension -1) in the boundaries of cells. Otherwise, the empty cell is considered a valid cell, and, as a result, reduced homology will be computed instead of plain homology. Note: The presence of the empty cell may cause problems while interfacing with the CHomP library, which assumes no empty cell presence.
