Function is_palindrome 

pub fn is_palindrome<T: PartialEq>(v: &[T]) -> bool

Returns true if the array / vector is palindrome.

Examples

let array1 = [8, 2, 2, 8];
assert_eq!(jabba_lib::jvec::is_palindrome(&array1), true);

let array2 = [2, 0, 2, 2];
assert_eq!(jabba_lib::jvec::is_palindrome(&array2), false);

let v = vec!["aa", "bb", "aa"];
assert_eq!(jabba_lib::jvec::is_palindrome(&v), true);
