Implementation of a no-op Tracer that I can in an interim until I rework tracing
to not be tied as a member of a Store (more generally useful by the application)
Added method to PersistentStores which will deserialize all Stores in the
Accumulo table for the purposes of the optiq impl to list all "tables" in the
"database"
Implement the initialTables method in CosmosDriver using the
PersistedStores.list method. This will auto-populate all "tables" that are in
the given instance.
Some tests for the PersistedStores.list method
Used Cobertura to identify a bunch of code in CosmosImpl which lacked
any test coverage yet were simple to test.

- Found some bugs where I double-stop()'ed a Stopwatch
- Paging incorrectly took a Long where it should have taken an Integer
(to prevent int overflow)
- Changed the thread/core options on failsafe to be less aggressive
- Unified setNumTservers invocations
Rework the argument parsing for CosmosConsole to better represent the
functionality of the minicluster and a real instance, respectively.

Also fixed up some depedencies that weren't properly declared in
cosmos-project's dependencyManagement block.
Rework the toString() on SValue because I didn't like that the
visibility came first
Adding a first stab at a formatted table for the cosmos console.
Make it even more mysql-esque by adding in a summary at the end of each
table which describes how long the operation took
Renamed the 'repl' into a 'console' since that's what I ended up calling
it all along
Remove dead code and fix the maven-exec-plugin invocations
Set up a locality group for the 'primary key' for each document
(COSMOS_DOCID).
Add the ability to pass through the BatchScanner/BatchWriter
configuration options to Cosmos via Store, #3

Created getters/setters for a BatchWriterConfig member to "tweak" writes and a
readThreads member that controls the maximum number of threads Cosmos
will use with a BatchScanner.
Deleting two useless classes that have been hanging around for a long
time. Also missed a replacement for a constant int with the value
defined on the Store in PersistedStores #3
Merge branch 'master' into costEstimation

	sql/src/test/java/cosmos/sql/TestSql.java
Added antlr grammars, updated CosmosStatement to provide greater extensibility
for additional sql constructs ( right now only show tables ). Will be updating
cosmos driver
Updating CosmosSQL to better support falling back to Optiq in the event
that the antlr grammars do not match
