PEL: SRC callouts subsection object
This Callouts class represents the optional subsection of an SRC PEL
section that contains FRU callouts. It is only present in the SRC when
there are callouts, and it comes at the end of the section.
It is basically just a container for the Callout objects that represent
the actual callouts.
