Detailed Description

A simple class for measuring CPU time.

The reson for the existence of this simple class is the fact that on Linux the CLOCKS_PER_SEC macro is equal to 1e6/second so that the clock() function, which returns the CPU time in units of CLOCKS_PER_SEC runs out only after about 40 minutes on 32 bit systems where an unsigned 32 bit integer variable is used. This is not very long for a Monte Carlo simulation.

Should add wall time measurement
