/**
+ * SenseStoreAndForward is a threaded implementation of an application that takes
+ * various sensor readings in parallel (by dedicating one thread to each reading),
+ * logs them to flash, and then sends them out over the radio at some later time.
+ * In the current implementation, sensor readings are taken as quickly as possible,
+ * and records containing a set of readings from each iteration are batched out
+ * over the radio every 10000ms. This application is written specifically for use
+ * with the tmote onboard sensor package, and will not compile for any other
+ * platforms.
+ *
+ * Readings are taken from each of the 4 oboard sensors and logged to flash as one
+ * record in an infinite loop. Records are then read out of flash and and sent out
+ * over the radio interface in separate infinite loop. Before the application
+ * starts running, the entire contents of the flash drive are erased.
+ *
+ * A successful test will result in LED0 remaining solid for approximately 6s while
+ * the flash is being erased. After that LED0 will toggle with each successful set
+ * of sensor readings logged to flash, at a rate of approximately 220ms (the time
+ * it takes to take a humidity + temperature sensor reading since they share the
+ * same hardware and cannot be taken in parallel). Also, LED1 will begin toggling
+ * in rapid succession once every 10000ms as records are successfully read from
+ * flash and sent out over the radio. Once all of the records currently recorded
+ * to flash since the last batch of sends have been sent out, LED2 Toggles to
+ * indicate completion. This process continues in an infinite loop forever.
+ *
+ * Additionally, a base station application should be run to verify the reception
+ * of packets sent from a SenseStoreAndForward mote, with reasonable looking sensor
+ * data.
