Description

hoomd.box.Box.from_box method mentions dimension attributes and keys as valid indicators of dimension for conversion to a Box object. This is not true and needs to be changed.

This is a good first issue for someone looking to do some C++ coding and contribute to EGSnrc. If you decide to give it a go, comment below so we know you are working on it, and feel free to ask for help.

The idea is to add bounding boxes to the egs++ geometries, to facilitate checks on whether two geometries might intersect, among other things. The egs++ geometries are found in `HEN_HOUSE/egs+

In #672 and #624, we discussed how the Steinhardt order parameter treats particles with zero neighbors. Steinhardt assigns a value of NaN. We need to check to see how other methods (Hexatic, Translational, SolidLiquid, LocalDescriptors) handle cases with zero neighbors.

The follow-up PR would basically be to review freud for other methods where this problem could arise and copy over the tes

The attr ranges could accept an interval of chars (according to ASCII). The attr ranges are mainly used by the plugins to define their attributes, e.g., see the attributes of this plugin.

The examples below could be
