// Various properties of the voxel types can be expressed via types traits, similar to the way std::numeric_limits is implemented.
// This has some advantages compared to storing the properties directly in the voxel class. For example, by using traits it is possible
// to also apply these properties to primative types which might be desirable (the Volume classes do accept primative types as template
// parameters). Also, properties such as minDensity() and maxDensity() would be difficult to represent though class members because they
// depend ont the type (float has a very different range from int8_t for example).
//
// The properties are currently exposed as constants because we need access to them at compile time. Ideally we would like to make them
// functions flagged with 'constexpr' as we could then make use of the max() and min() functions in std::numeric_limits, but this is not
// widely supported by compilers yet. We may change this in the future.
