Doc and comment improvements
Index into vectors using integers.

This commit corrects an error that has been present since the
introduction of function wellsToSrc() in commit a50bb8f but was never
detected.  Although the conversion int->double->std::size_t is likely to
be loss-less, it is better to not introduce any more steps than are
actually needed.
