Detailed Description

Subclass of TaskRunner for handling intrinsically paired visits.

This transforms the processed arguments generated by the ArgumentParser
into the arguments expected by tasks which take visit pairs for their
run() methods.

Such tasks' run() methods tend to take two arguments,
one of which is the dataRef (as usual), and the other is the list
of visit-pairs, in the form of a list of tuples.
This list is supplied on the command line as documented,
and this class parses that, and passes the parsed version
to the run() method.

See pipeBase.TaskRunner for more information.
