simList.makeDigestible(simList)
## S3 method for class 'simList':
makeDigestible(simList)simListsimList object, but with no reference to any environmentssimList, except that all references to
local environments are removed. Specifically, all functions (which are contained
within environments) are converted to a text representation via a call to format(fn).
Also the objects that were contained within the .envir slot are hashed using digest
in the digest package. Also, paths slot is not used to allow
comparison across platforms and it is not relevant where the objects are gotten from,
so long as the objects are the same. The .envir slot is emptied (NULL). The object is then
converted to a simList_ which has a .list slot. The hashes of the objects
are then placed in that .list slot.cache.
