------------------------------------------------------------
Added new patches:
# [removeDescendantsAndSelf|^removeDescendantsAndSelf-api-take2.patch] - the
api would now always remove documents breadth wise upwards. The maxDepth is
calculated by jumping exponentially up and then zero-ing using binary search
# [cleanupDisabledIndices|^cleanupDisbaledIndices-take2.patch] - there is now
just one exposed method {{cleanupDisabledIndices}}.
Some examples usages of {{cleanupDisabledIndices}} are:
{noformat}
//Generate and print list of currently disabled index names.
//Then use that list to continue in dryMode.
> oak.cleanupDisabledIndices()
Generated index names: ["disabledIndex1", "notToBeCleanedDisabledIndex1",
"disabledIndex2"]
//validate index names to be cleaned up
> oak.cleanupDisabledIndices(["disabledIndex1", "enabledIndex",
> "disabledIndex2"])
...
Index enabledIndex is NOT DISABLED
...
//carry out actual cleanup
> oak.cleanupDisabledIndices(["disabledIndex1", "disabledIndex2"], true)
Deleting tree at path /oak:index/disabledIndex1/:index
Deleted 12 documents in 2ms
...

> While disabling property indices, avoids usage of those indices. But, they
> still maintain the data already stored under them. That data would keep on
> consuming storage space without serving any purpose. Also, it'd pile on
> mongo's id index.
> While one can delete index definition node to clear these nodes up -- but,
> it'd be really slow and a JCR based deleted would first create a HUGE commit
> while marking all documents under it as deleted. And, then the actual
> deletion would happen in next revision GC after 24 hours have past.
> Hence, it might be beneficial to have a low level api in oak-mongo.js, which
> simply removes the document from mongo altogether.
