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
Interactive tool for testing out regexes, really neat. 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.
