Added basic implementation of Parallel::For.
Uses almost identical implementation to Parallel Foreach but doesn't defrerence the index type it is passed, expects an int or similar, not an iterator
Added python stuff to .gitignore for new test script, added CMake command to build a testing build, added Parallel::For input parameter and added Parallel::For test code.
Added multiple build configurations to support debug, release and profiling builds and switched to out-of-source builds.
Merge branch 'feature/ParallelFor' into develop
