Particle energy quantities
These energy quantities are tied to util::quantities::units::ElectronVolt. A few options are provided: most general template, scaled_electronvolt, allowing to choose both the scale of the unit (e.g. std::exa for exaelectronvolt) and the type of the numerical representation generic templates (e.g. electronvolt_as), allowing to choose which numerical representation to use double precision (e.g. electronvolt), ready for use
