[cs63201] clarifications for Project 1

[Mikhail Nesterenko]

Dear AOS students,

To represent seconds, do not use floating point type.  Instead, define
a range of integer values to represent seconds and use signed or
unsigned integers to store time values. Note that TinyOS timers accept
uint32_t.

Also, for people who are using our lab machine: ws07.month.cs.kent.edu
If you want to look at TinyOS code, it is located in /opt/tinyos-1.x/

thanks,
