SE 3800 Cube Example: testing with coverage

This code uses a trivial function to illustrate adding tests and collect statement coverage with makefiles. To use this in Linux, you will need

        sudo apt-get install -y libgtest-dev lcov
        cd /usr/src/gtest
        sudo cmake CMakeLists.txt
        sudo make
        sudo cp *.a /usr/lib

The files:

• cube.h, cube.cpp, main.cpp: main program
• cube_test.cpp: code to test cube.cpp
• Makefile: build, generate coverage
• SmallerMakefile: a makefile that uses variables and implicit dependencies to avoid some of the repetition. Use this as

          make -f SmallerMakefile
  

  (or simply rename it to Makefile)
• Vagrantfile: vagrant setup, complete with building test libraries
