Review Comment:
The initialData is a list of entries to be stored in the ordered list, which
is an idea borrowed from the MultimapUserStateTest.
An entry is specified by the value and a state key (including the name of
the state and the range this entry will fall in). Multiple entries may belong
to the same state because only the name of the state is the identifier.
When we need to put these entries in the internal structure, we will remove
the range field in the state key so that entries of the same state identifier
will be put into one bucket.
