Regular expression is a way to check the format or content of a string.
Regular expression are entered within slashes. An 'i' after the slashes means a Ignore case when searching, while a 'g' means a global search (i.e. find all iterations of the regular expressions in the field).
In this excercise we will ask the user to tell us what they're looking for, and in what, and then we will tell them if a match was found or not.
