…printf style format statements as well as comparison against snprintf results

It's pretty interesting to see how boost behaves differently on linux and windows using this tool.

Even snprintf is different between recent standard runtimes. Surprising! |

added a matrix tool that allows for version-to-version comparison of printf style format statements as well as comparison against snprintf results
The result file generated by the tool has about 60,000 variations of format strings.
One can use it to compare snprintf output from one version of a RTL to another, or to compare boost::format output from one version to another (to look for regressions), or to compare snprintf to boost::format.
The
WinMergeprogram does a nice job comparing two output files from this tool as you will see in some of the comments below.Once this tool is in place, it can be used to establish a a baseline before making any changes to the codebase, and then running it again and comparing the result to see if those changes resulted in a regression.
This fixes #33
