00002  * Main class for the project.
00003  * The main class instantiates all the tasks and schedules them
00004  * correctly using the TaskManager object.
00005  *
00006  * As writing to the SDCard occasionally hits +50ms in timing, there was several issue
00007  * with the schedule purposed in the original assignment. As a result the timings have changed.
00008  * 
00009  * Action 2 (reading digital values) have been discarded. The values are only used
00010  * in the Action 5, as a result we might as well read them "Just In Time". 
00011  * However if desired it could have been scheduled starting at 600ms with a freqency of 600ms
00012  * 
00013  * The schedule is as follows:
00014  * Action 1 (frequency)           1200ms
00015  * Action 2 (get digital input)   disabled, see above
00016  * Action 3 (read analog in)      600ms
00017  * Action 4 (Print to LCD)        1200ms
00018  * Action 5 (checks)              600ms
00019  * Action 5.1 (binary counting)   1800ms
00020  * Action 6 (SDCard)              4800ms
