Initial TODOs

[mandyedi]

I'm using this issue to track tasks until the base project and all the necessary tools and processes are set up.

Folder structure:

cppfront
  include
  src
docs
examples
src
test

• Setup cmake
  https://github.com/modern-cmake/cppfront
  https://github.com/filipsajdak/Cpp2-Example

• GoogleTest
  http://google.github.io/googletest/quickstart-cmake.html

• Syntax highlight
  https://github.com/hsutter/cppfront/wiki

• Examples
  First: only simple code examples
  Later: a small program that renders the loaded object (SDL/SFML, https://glad.dav1d.de)
  Later: example for every implemented feature

• Use modules
  Study C++ module feature
  Are there headers?
  How can I use modules with legacy code (that uses include)?

• Multiple cpp2 files
  Projects with multiple cpp2 files hsutter/cppfront#1344
