Sample Vapor/Heroku Project with Request calls in the Routes handler.

This was originally generated using the Vapor Toolbox and edited using Xcode.

1. Added Heroku Procfile, as autogenerated by Vapor Toolbox.
2. Set Heroku Buildpack to: https://github.com/vapor-community/heroku-buildpack.
3. Added Heroku remote Git repo link.
4. Currently Heroku's Vapor Buildpack requires LinuxMain.swift to build. This can be worked around by adding the SWIFT_BUILD_FLAGS Env Var.

echo "web: Run serve --env production --hostname 0.0.0.0 --port \$PORT" > Procfile
heroku config:set SWIFT_BUILD_FLAGS="--enable-test-discovery"
heroku git:remote -a hellovaporhk
