Add timing to the output from ConnectedComponents example.
Removed startup logging message from stderr.
Made the examples work more intutively in multiprocess mode: all input is now collected from process zero.
Added an experimental serialization mode, which can be enabled by passing "--inlineserializer" on the command line. The new serializer (i) generates more efficient code for primitive types and structs of primitive types, and (ii) falls back to using .NET serialization in the event that it cannot generate efficient code.
