 * This script basically just runs through all source files and
 * prints out a list of files and lines where it found the TODO
 * keyword
 *
 * If you want to look for other keywords, just changed the
 * searchRegEx to your needs :)
 *
 * If placed in your projects you can set it up as a script in your
 * package json and run it like this:
 * npm run todos
