Issue DM-2424: Create transitional duplicate of Span
One challenge in switching from {{PTR(Span)}} to {{Span}} in {{Footprint}} is that Swig won't generate wrappers for {{std::vector}} (or any other container) if {{%shared_ptr(Span)}} is used anywhere else in the codebase. So, to allow both the old {{Footprint}} class and the new {{SpanRegion}} to coexist (temporily), we need to have two {{Span}} classes, one wrapped with {{%shared_ptr}} and one wrapped without it. Since we don't want to disrupt the old {{Footprint}} class yet, we should call the new Span something else, and make it the one that's wrapped without {{%shared_ptr}}. This ticket can be considered complete once we have a unit test demostrating a usable Swig-wrapped {{std::vector}} while all old {{Footprint}} tests continue to pass.
