+*  Using the JavaScript language, have the function ABCheck(str) take the str          *
+*  parameter being passed and return the string true if the characters a and b are     *
+*  separated by exactly 3 places anywhere in the string at least once                  *
+*  (ie. "lane borrowed" would result in true because there is exactly three characters *
+*  between a and b). Otherwise return the string false.                                *

+*  I am goint to use a RegExp to see if the patter [a...b] exists anywhere in the      *
+*  string. If it does then return true else return false.                              *
