func_documentation_string: ISSORTED // 
  FUNCTION: issorted( arr[, comparator] )
  Returns a boolean indicating if an input array is sorted.
  
  @param {Array} arr - input array
  @param {Function} [comparator] - comparator function invoked for each pair of consecutive elements which returns a numeric value indicating if elements are ordered
  @returns {Boolean} boolean indicating if array is sorted
