[Users] dependencies & CST warnings

To my knowledge these routines implement the old-style boundary routines
for octant, quadrant, bitant symmetry (ie if cartgrid3d::domain is not
"full"). The thorn would run fine without and in fact using those
options is deprecated (in favor of ReflectionSymmetry which does require
SymBase which does require Boundary). Having said that, I would not
*want* to run without Boundary on grounds of not knowing which thorns
silently assumes it is present, but it is not required for CartGrid3D
(eg the wavetoysimple example does not use it).

Yours,
Roland
