helper function for easily removing a resource by ID

[LiNk-NY]

Hi Lori, @lshep

Perhaps it would be good to have an un/exported helper function to remove a single resource from the cache for those of us that have a corrupt cache or are doing some testing/debugging. A starting example is below based on the instructions you provided on Slack:

.removeCache <- function(hubID, dry.run = TRUE) {
    eh <- ExperimentHub()
    cache <- hubCache(eh)
    bfc <- BiocFileCache(cache)
    ## query the cache to determine the BFC ID
    rid <- bfcquery(bfc, hubID)
    if (dry.run) {
        message("Resource not removed. Use 'dry.run = TRUE'")
        rid
    } else
        bfcremove(bfc, rid$rid)
}

Agreed seems useful. Might take me a week or two to get to this but I'll look at adding asap.

It looks like this is already implemented through the hub class. "removeResources"

Ill add it to the AnnotationHub-class and ExperimentHub class documentation

[lshep]

actually its already documented

Ah, sorry I missed it. Thanks for looking into it!
