Changed projection point in time to before sampling. Good results similar to original paper are achieved.

Added distFromSol as member variable and public functions for accessing the final iteration, change, residual and number of points in the NB.

Deleted options for higher order upwind gradient from the Sussman redistancing because I cannot show numerical convergence for these.

Changed convergence criteria of Sussman redistancing, writing out with higher precision, having a check if NB already contains points. Backing up state before removing WENO/ENO option.
