Event data, describing the indexes that were added/removed/updated, and providing access to Rows (and thus data
in columns) either by index, or scanning the complete present index.
This class supports two ways of reading the table - checking the changes made since the last update, and reading
all data currently in the table. While it is more expensive to always iterate over every single row in the table,
it may in some cases actually be cheaper than maintaining state separately and updating only the changes, though
both options should be considered.
The RangeSet objects allow iterating over the LongWrapper indexes in the table. Note that these "indexes" are not
necessarily contiguous and may be negative, and represent some internal state on the server, allowing it to keep
track of data efficiently. Those LongWrapper objects can be passed to the various methods on this instance to
read specific rows or cells out of the table.
