Rename grahamConvexHull2d3d to grahamConvexHull<2>,
deprecate old interface.

Dennis Gläser authored 5 years ago and Timo Koch committed 5 years ago

This actually makes use of the 2d in 3d algorithm at the moment. In the
future a more efficient implementation for 2d hulls could be
implemented.

[staggered][fluxVars] Adapt treatment of interior boundaries

[test][convergence] Change condition of checking error i twice to checking...

See merge request !1634

* so far, interior boundaries (e.g., flow around a block)
  were always interpreted as Dirichlet (no-slip) boundaries
* the reduced distance used in the calculation of the gradient
  was already correctly incorporated, we just document it better here
* this concerns the gradient for the shear stress term, e.g., du/dy
  at an edge within the domain

[test][convergence] Change condition of checking error i twice to checking error i and error i+1 once.

Before this change user defined defaults are overwritten by the
global defaults if init is called twice. Now global defaults are only
applied if the parameter doesn't already exist.
