Method open

src/main/java/field/graphics/MeshBuilder.java:65–86

opens a MeshBuilder to get it ready for accepting geometry. The first call to open() will clear out all the geometry that was previously in this container. Nested calls to open() without a corresponding call to close() will append. Make sure that there's a matching close() for every open() (i.e. lea
