467c2fb89c Allow a boolean to be passed in to set IndexModDate 
Although we are still pre-release in Leveled, for completeness it is a useful test of this code change to show that it can be done in a backwards compatible way.

So a boolean is added to indicate whether a file should index the modified date within the slot, and this can then be read when the file is opened.

Nothing happens with the boolean, yet.

baa4466923 Remove knowledge of tuple length from ledger value 
Nothing should now care about the current tuple length - and hence the tuple length may be increased (for example to add a max_mod_date)

4981cdfc07 Expand segment lists when matches are produced form smaller trees 
Let us say a store has precalculated segments based on large tree size, but mismatched segmentIDs are found on a small tree size (for query efficiency).

the list of segment IDs need to be expanded out for matching.  This may be more efficient that running match_segment for each check (expand out once and uses lists:member/2).  Also this is necessary for leveled_so AAE stores (segment-ordered stores)

88e4cf2361 Add unit test with bad write 
If a partial write is made at the beginning,  the file was not being truncated.  Consequently writes would be accepted after it opens, and the those writes would be after the corruption so would never be read in the future.

bed155761b Added comments 
This is still a clumsy feature, in terms of implementation.

Is the fact that some folds handle a throw, and some don't an issue?

f12d277875 Update docs for start key 
Quviq/leveled/issues/13 shows the confusion around the purpose of
start key. Hopefully this commit clarifies that start key is a further
refinement to the range start. It's essentially and AND.

5a95e82af0 Callers of bucket list expect the traversal to be in order 
Due to the internal fold over buckets returning an un-reversed
accumulator, the API bucketlist code caller's fold fun traversed the
bucket list in reverse order. This lead to some inconsistencies when
comparing a buckelist of all buckets, vs, first bucket only. i.e. the
'first' bucket passed to the foldfun was in fact the last bucket read
from the ledger.
