// Specify Upper and Lower Number of Matches
/*
Quantity specifiers declared with curly brackets {}
allow matching to occur a required number of times. 
The + is used to match one or more and * is for 
matching zero or more times.

To match only the letter a from three to five times in
the string ah, the regex would be /a{3,5}h/.
