Make bench.out in json format
This patch changes the output format of the main benchmark output file (bench.out) to an extensible format. I chose JSON over XML because in addition to being extensible, it is also not too verbose. Additionally it has good support in python. The significant change I have made in terms of functionality is to put timing information as an attribute in JSON instead of a string and to do that, there is a separate program that prints out a JSON snippet mentioning the type of timing (hp_timing or clock_gettime). The mean timing has now changed from iterations per unit to actual timing per iteration.
