Detailed Description

template<class T>
class celeritas::Range< T >

Proxy container for iterating over a range of integral values.

Here, T can be any of:

an integer,
an enum that has contiguous zero-indexed values and a "size_" enumeration value indicating how many, or
an OpaqueId.

It is OK to dereference the end iterator! The result should just be the off-the-end value for the range, e.g. FooEnum::size_ or bar.size().
