This is intended to be used within the
Cache function, but can be used to evaluate what
simList would look like once it is converted to a repeatably digestible object.
# S4 method for simList .robustDigest(object, .objects, length, algo, quick, classOptions)
an object to digest.
Character vector of objects to be digested. This is only applicable if there is a list, environment (or similar) with named objects within it. Only this/these objects will be considered for caching, i.e., only use a subset of the list, environment or similar objects. In the case of nested list-type objects, this will only be applied outermost first.
Numeric. If the element passed to Cache is a
object (from e.g.,
asPath(filename)) or it is a
file-backing, then this will be
digest::digest, essentially limiting the number of bytes
to digest (for speed). This will only be used if
quick = FALSE.

This method strips out stuff from a
simList class object that would make it otherwise not
reproducibly digestible between sessions, operating systems, or machines.
This will likely still not allow identical digest results across R versions.
