Raw TCP operators and integration with Boost ASIO.  The operators themselves aren't well motivated at this point (ncat like functionality) but are just serving as a testbed for how to integrate the dataflow scheduler with an event demuxer like ASIO
Developing an HTTP request parser with goal of implementing an HTTP interface into a flow
CMake for in development HTTP support
Initial implementation of an HTTP post operator
Query string parsing operator
CMake for query sring operator
Fixed some bugs in the query string parser
Two new pieces of functionality.  First is the ability to have an operator request a mix of read and write requests.  The second is the ability of the scheduler to flush partially full local write buffers.  It does this prior to any blocking IO waits so we get low latency processing even when there isn't a big fat stream of data pushing things through.  The current implementation of this idea is rather simplistic and more experimentation will be necessary to see if it navigates the latency/throughput tradeoff curve successfully
Have the HTTP read operator properly use the new API for requesting a mix of reads and writes to fix some pretty broken behavior in how this was working previously.
Handle query strings with newlines and treat these as multiple query strings so that we can handle Akamai aggregated download receipts.  I'm not sure if such functionality makes good sense in general but it seems to be necessary.  Also fixed egregious memory leak.
Maintain a few internal statistics in the scheduler that help one understand the IO service behavior
