Write this program in Scala.

Write and test a simple palindrome detector:

isPal("rotator") => true

isPal("cat") => false

isPal("Rotator") => false

isPal(" rotator ") => true

isPal("r0tat0r") => true

etc.

Note: isPal should ignore leading and trailing whitespace. It should also be case sensitive. It should work even if the string contains characters other than letters.
