new test for NormalToMeshProjectionBoundary added

new test for NormalToMeshProjectionBoundary added

Fixed indentation.

Attempt to fix create tria test.

Second attempt. This is the correct output.

Added create_tria_00.

Added supersimple test.

attempt to fix the normal projection tests that were failing by switching to wigley.igs surface (instead of side.igs which seemed to have something weird)

switching to wigley.iges in create_tria_01.cc too

added test normal_to_mesh_projection_02.cc on surface mesh refinement with projection normal to mesh direction. in the process, this highlited a bug in the boundary_lib.cc implementation of normalToMeshBoundary. Now also the results of step-54 look even better

Fixed output for iges write functions.

Added two simple tests.

Fixed a little the documentation, and improved slightly step-54.

Fixed indent.
