*
* This class allows the user to trace the memory charge between the execution
* of two pieces of code. It can be started and stopped in order to evaluate
* the execution over multiple passes. The values of memory are taken from
* GetProcessMemoryInfo() for Windows, the SMAPS file for Linux
* and getrusage() otherwise.
