Add TypeConfigurable interface for output formats.
Minor cleanups.
Input formats can tell their types to the java data set (no need for double manual configuration)
Collections on tuples need no manual type information
Additional sanity checks
Renamed type configurable/queryable interfaces to more intuitive names
Avro input format provides type for the produced data set.
Additional fail fast checks for new java api.
Adjusted Avro Input Format for new Java API.
Adjusted test case for externally packaged avro program.
added util tests
included examples source code into assembly
Integrated Bootstrap in the User Interface and made some improvements and code clean ups.
Added kmeans as an example for the new java api.
Rename typo (Buffe -> BuffeR in SerialSingleBufferPool)
Early return if no receiver found for envelope in dispatchFromNetwork(Envelope)
Unwrap chained task exceptions and add magic number to envelope for data stream integrity checks
Overwrite stateful methods of BufferWriter in RecordWriter to ensure correct data and event ordering
Minor renaming of serialization classes to include 'Record' in their names
HadoopDataSink works both for hadoop 1.2.1 and 2.2.0
add license headers
add ContextCheck to LocalExecutor; check in HadoopDataSink for output path
automatically generate a javadocs page
Discard envelopes with neither buffer nor event attached at InputChannel

Fixes the following problem: serialization in RecordWriter might result in sending
of empty buffers (e.g. writer sends out a full buffer, requests a new one, and then
gets flushed), which then causes an error at the receiving InputChannel, because of
an envelope with neither buffer nor event attached.
Add project operator to Java API
