This leads to a substantial speed up in the intersection time
measurement test for the empty intersections.
TODO: We could introduce a compile-time option to allow users to
deactivate this upon configuration. Because, in case one knows that
almost all entities that will be created will intersect, the query is
obsolete. However, for sparse distributions of entities, this will
speedup constraints evaluations significantly.

For now, this is just an alias for the Box class, but in case the Box
class is extended at one point to be more general, i.e. to allow for
non-axis-aligned boxes, it wouldn't serve as an implementation for
bounding boxes anymore. To this end, we now introduce this alias which
allows us to mark interfaces that require bounding boxes to be passed to
them already at this point.

[multigeometry] exit loops in lambdas after success

Feature/constraints eval for set

See merge request tools/frackit!91

[geometry] make all geometries default-constructible

See merge request tools/frackit!89

This could be usefol, for example, in the case that one passes
geometries as references to a function in which they are actually
created. At the point of creating these objects in order to pass them to
a function one might not have enough data/information to actually
instantiate them.

Fix/clang compilation issues

See merge request tools/frackit!88

This led to linker errors using clang, removing it made it work with
both clang and gcc.

This failed to compile using clang.
