"""
Static Analyzer qualification infrastructure: adding a new project to 
the Repository Directory.

 Add a new project for testing: build it and add to the Project Map file.
   Assumes it's being run from the Repository Directory.
   The project directory should be added inside the Repository Directory and 
   have the same name as the project ID
   
 The project should use the following files for set up:
      - pre_run_static_analyzer.sh - prepare the build environment.
                                     Ex: make clean can be a part of it.
      - run_static_analyzer.cmd - a list of commands to run through scan-build.
                                     Each command should be on a separate line.
                                     Choose from: configure, make, xcodebuild
