Find the palindromes
------------------------------------------

Implement a function that finds all palindromes in a string variable. A palindrome is a word that is the same when read backwards, like "madam", "civic" or "radar". Here, the palindromes do not need to be actual words; "aa" and "abcba" count as palindromes. Note that "bcb" in the center of "abcba" counts as a separate palindrome. Single letters do not count as palindromes.

Syntax: pals = palindrome(letters)
        -------------------------

where 	letters is a string variable,
	pals is the number of palindromes in letters
      
Example:

The palindromes in 'dafgfafaadarra' are

'afgfa', 'fgf', 'faf', 'afa', 'aa', 'ada', 'arra', 'rr'


Basic functionality:

>> pals = palindrome('dafgfafaadarra')

pals =

    8
