+*  Using the JavaScript language, have the function Palindrome(str) take the str       *
+*  parameter being passed and return the string true if the parameter is a palindrome, *
+*  (the string is the same forward as it is backward) otherwise return the string      *
+*  false. For example: "racecar" is also "racecar" backwards. Punctuation and numbers  *
+*  will not be part of the string.                                                     *

+*  I have two outliers. The first is to remove all spaces between words since it can   *
+*  cause the reverse string to be wrong. The second is to convert string to lower case *
+*  so that any capitalized words cause a false answer. I am going to first remove all  *
+*  spaces from the string. Then I am going to convert a new string that converts the   *
+*  modified str into an array and then reverses the contents and then converts it back *
+*  to a string. I will compare the modified string and the newStr to see if they are   *
+*  equal signifying I have a Palindrome.                                               *

+*  Steps for solution                                                                  *
+*    1) Modify str by removing all spaces and converting to lower case.                *
+*    2) Create a new string by converting modified str into an array, reverse it and   *
+*       then convert it back to a string                                               *
+*    3) Compare two strings to see if equal meaing I have a Palindrome                 *
