/**
 * ## Fill-In-The-Blank Regular Expression Graders
 *
 * For the FITB Regex grader, you'll need to be familiar with javascript regular expression syntax.
 * - Tutorial/Documentation at [https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions)
 * - Interactive tool for testing out regexes, really neat. [https://regex101.com/](https://regex101.com/) Make sure to select the "ECMAScript/Javascript" flavor on the left side.
 * - Tip: Normally, the regex will match against any substring of what the student entered. If you want it to only match the WHOLE thing, use `^` and `$`. For example, if you're looking to match any decimal number `/[\d\.]+` will match `6.2` and `My answer is 6.2`, whereas `^[\d\.]+$` will only match `6.2`. Essentially `^` means "beginning of string" and `$` means "end of string".
 *
 * For now, refer to examples of existing graders. More thorough documentation coming.
