Changes to account for the field ordering. Now correctly inserting and
updating field values so that they can be verified when using
dataintegrity=true.

Fixes #132

- define checkstyle configs in as few places as possible
- use checkstyle:check since it has defaults that match what we want (fail after logging to console)
- modules that have current failures set property checkstyle.failOnViolation to false.

* Cleaned up javadoc and comments
* Backed out unnecessary line breaks
* Updated license

Closes #494

[cassandra cassandra2 dynamodb hbase098 hbase10 jdbc s3] Fixing squid:S1481 - Unused local variables should be removed

reverted a few things that were not necessary
* semicolon change - coming in another PR
* .gitignore change - no longer using derby

Code cleanup
* test scoped hsqldb
* removed derby artifacts and references
* setting driver class is not necessary
* cleaned up unused objects in delete
* now running cleanup on client
* removed old assert(true) stub

Had to fix the semicolon issue for Derby.
Ended up switching to HSQLDB becuase Derby does not support LIMIT.

Also fix a few README formatting issues.

        mvn org.apache.rat:apache-rat-plugin:0.11:check -D rat.numUnapprovedLicenses=5000

Replaces numeric status codes with a canonical set of Status objects,
each with a short name and description.
Bindings with more specific errors (e.g., timeouts) return additional
statuses.

This changes the default output from messages like:

   [UPDATE], Return=0, 511

To:

   [UPDATE], Return=OK, 511

This will ensure record ordering my the primary key.

Now properly enforcing a scan of the given number of documents in the
scan operation using the LIMIT modifier in the cached statement.

Fixes #171.

Fixes #459

Fixes #438

As a part of branching to stage 0.2.0 release in #266, set version
for continued development on master branch.

* remove unused declared deps in a few places
* lex sort modules in top level pom
* update maven plugin versions.
* no more jar-with-dependencies
* set ycsb-core to provided in bindings
* introduce a bindings-parent pom that sets
** stage dependency copy on building binding
** iff binding has a README.md, build a binding-specific dist artifact
* update distribution assembly to
** properly build after modules
** use per-binding sets of dependencies

closes #250

* Need a SNAPSHOT version because non-SNAPSHOT is reserved for actual releases.
* Increment minor version per pre-1.0 guidelines from the Version Numbers guide

Fixes #236.

JDBC scans did not instruct the driver to use a specific fetchsize,
resulting in most cases in an OOM; add support for setting fetchsize.

Also add support for disabling autocommit on the JDBC connections,
mostly because Postgres for example doesn't support setting fetchsize
without disabling autocommit.
