First, simple per-edge TTL implementation
Sketch of per-label TTL implementation
First working per-label TTL
Added unit tests for per-edge and per-label TTL on embedded Cassandra
Completed unit tests for TTL on Cassandra (embedded, Thrift, and Astyanax)
Added test case to ensure that edges disappear from key indices after TTL
Resolved merge conflicts and adjusted to Titan management API
Vertices isolated by TTL currently do *not* expire from the graph
Brought TTL up to date with titan05 HEAD
Resolved conflicts since last merge
Merge branches 'titan05' and 'ttl' of https://github.com/thinkaurelius/titan into ttl
Use EntryMetaData to both get and set TTL
Use int, not long, for TTL, following the Cassandra APIs. 68 years is a good, long life for a cell
Treat TTL as int-valued property in ImplicityKey, with a unit of seconds
Resolved merge conflict
Restored simple TTL unit tests
Added diskstorage-level TTL test
Test TTL at the KeyColumnValueStore level, though currently enabled only for Cassandra
Support for TTL and other type modifiers TitanManagement (in progress)
Merge branch 'titan05' of https://github.com/thinkaurelius/titan into ttl
