Subject: This CL adds bookkeeping structures for routing, including the
 routing buffer, routing index buffer, and the routing table. It also adds the
 main routing function, slave-side implementation of receiving subscribed data
 and master implementation of managed data in the routing buffer. This CL
 supports only routing data (branch 1) and only honors subscriptions based on
 module ID. CL also adds minor changes to the dataflow process, including
 inserting data into the routing buffer and incrementing routing pointer. CL
 also adds a configuration macro MASTER_I2C_BUS_INTERVAL in config.h to delay
 master I2C operations in order to minimize I2C timeout errors on the bus.
