Add a command to access the system timer
Two sub-commands... start and get.
* start sets the reference.
* get prints out the time since the last start (in "<sec>.<msec>" format).
If get is called without start, returns time since boot.
Simple way to benchmark an operation: "timer start;<commands-to-measure>;timer get"
