/*  E-MAIL VALIDATION FUNCTION
Every email is made up for 5 parts:

   1. A combination of letters, numbers, periods, hyphens, plus signs, and/or underscores
   2. The at symbol @
   3. A combination of letters, numbers, hyphens, and/or periods
   4. A period
   5. The top level domain (com, net, org, us, gov, ...)

Valid Examples:

    * bobby.jo@filltank.net
    * jack+jill@hill.com
    * the-stand@steven.king.com

Invalid Examples:

    * @deleted.net - no characters before the @
    * free!dom@bravehe.art - invalid character !
    * shoes@need_shining.com - underscores are not allowed in the domain name

The regular expression to check for all of this is a little overkill and beyond the scope of this tutorial to explain thoroughly. However, test it out and you'll see that it gets the job done.
