+*  Using the JavaScript language, have the function NumberSearch(str) take the str     *
+*  parameter, search for all the numbers in the string, add them together, then        *
+*  return that final number. For example: if str is "88Hello 3World!" the output       *
+*  should be 91. You will have to differentiate between single digit numbers and       *
+*  multiple digit numbers like in the example above. So "55Hello" and "5Hello 5"       *
+*  should return two different answers. Each string will contain at least one letter   *
+*  or symbol.                                                                          *

+*  I only want numbers in the string so I am using RegExp to remove everything that    *
+*  is not a number. Then convert that to an array. Loop thru each number in the array  *
+*  and add tot to get the answer.                                                      *

+*    1) Initialize tot to zero                                                         *
+*    2) Remove everything but numbers from string and convert to array                 *
+*    3) Loop thru each number in array and add to tot                                  *
+*    4) Return tot for answer                                                          *
