These options allow you to write the output of a benchmark to the specified
file and with the specified format. The goal of this change is to help support
tooling.
* Add test for reporter output.
* setup err_stream tests
* Fix warnings in tests
* whitespace
* Fix build errors caused by super pedantic compilers
* Pass streams by pointer not non-const reference
Benchmark library builds and runs but only single-threaded. Multithreaded
support needs a bit more love.
Currently requires some C++11 support (g++ 4.6.3 seems to work).
