/**
Summary: Compute whether derived files are up-to-date

Syntax: revIDEIsFilesetStale(pInputs, pOutputs, pRecursive, rError)

Parameters:
pInputs: A numerically-keyed array of filenames, or a filename
pOutputs: A numerically-keyed array of filenames, or a filename
pRecursive: True if folders should be checked recursively
rError: Set to a string describing an error, if necessary.

Description:
Checks whether the <pOutputs> are up-to-date relative to the
<pInputs>, by checking the modification times on the files.  Returns
true if any of the <pInputs> are newer than any of the <pOutputs>, or
if any of the <pOutputs> are missing.  Returns false if all of the
<pOutputs> are up-to-date.

If an error occurs, returns empty and sets <rError> to a descriptive
string.

The <pInputs> and the <pOutputs> are file sets, and can either be a
single filename as a string, or a numerically-keyed array of filenames.
It is an error for either file set is an array with non-numeric keys, or
for any filename to be the empty string.

If either file set is empty, the return value is true.  It is an error
for any of the input filenames to be missing.

If <pRecursive> is true, any filename in the <pInputs> or <pOutputs>
that is a directory is scanned recursively and its files are added to
the fileset.  If <pRecursive> is false, it is an error for either file
set to contain directories.
