Comment (by hinder):

 Thanks for the patch.  I have the following comments:
 * There is some debugging code left in, some of it commented out.
 Probably this should be removed.
 * The new keywords, VarExpABSTOL and VarExpRELTOL don't fit with the all-
 caps conventions of other keywords accepted here.
 * From looking at the code, it looks like you can only specify each of
 these once.  This means that you can only specify a variable-specific
 tolerance for the variables whose names match one regular expression, and
 only one tolerance value.  Unfortunately, this might not be enough in most
 of the cases where this would be used.  Is this correct?

 Maybe a better interface would be to use the existing ABSTOL and RELTOL
 keywords, but to allow two arguments.  The first would be the tolerance,
 and the second would be a regular expression determining which variables
 to apply this tolerance to.  It would default to '.*'.   Additionally, the
 mechanism would be extended so that more than one ABSTOL or RELTOL can be
 provided so that different variable patterns can have different
 tolerances.
