Following global procedures are defined:
initializes hi-res timers
Example:initialize()
randomize()
reset the random number generator
Description:The seed provided to the random number generator is an atom
calculated from a high-resolution time factor so it is very unlikely
to be the same at next launch
randomize()
initialize()
Following global functions are defined:
return a high resolution time since some fixed point in the past.
Return:an atom
t0 = hires_time()
