This directory contains a number of examples for generating grids with gridgen.example 0:	An estuary with two elongated channels.example 1: 	An estuary with one channel.example 2: 	Same as example 1 except the turning points placed at different 	locations. This produces a different result for the same boundary;	demonstrates how to implictely control the cell density by changing 	locations of the turning points.example 3: 	A shape from the CRDT paper.example 4: 	Use of non-right angles.example 5: 	Just for the sake of it.example 6: 	Same as example 5, with custom cell density.To build example grids,   1. Make `gridgen' in the upper level directory   2. Run:      makeTo visualize grids, in Matlab run:   viewallor, for a particular grid, use scripts viewgrid() and vg(), e.g.:   viewgrid('prm.0','v');   vg('grid.0');Good luck!Pavel Sakov
