/** \file
* This file contains indicator functions. These return 1 if the given
* coordinates are inside, and 0 if they are outside of the defined set.
* Implemented are :
- Sphere
- Cylinder
- Cone
- Pipe (not yet)
- Cube (not yet)
- Cuboid
- Circle
* The smoothIndicator functors return values in [0,1]. In particular there is
* an epsilon enclosure of the set, wherein the return values are smooth and do
* not jump from 0 to 1.
Boolean operators allow to create unions and intersections. They can be used
for example for initialization of a SuperGeometry.
