A wrapper on a trace, which given a snap, implements the {@link Program} interface

<p>
NOTE: Calling {@link CodeUnit#getProgram()} from units contained in this view may not necessarily
return this same view. If the code unit comes from a less-recent snap than the snap associated
with this view, the view for that snap is returned instead.

TODO: Unit tests for all of this.
