Add lang.types.String

[thekid]

Scope of Change

A new class lang.types.String will be added.

Rationale

Complement rest of the classes in lang.types.

Functionality

Classes currently in lang.types:

* lang.types.ArrayList
* lang.types.Number
  * lang.types.Byte
  * lang.types.Double
  * lang.types.Float
  * lang.types.Integer
  * lang.types.Long
  * lang.types.Short

New class lang.types.String (minimalistic because wrapper type):

<?php
  class String extends Object {
    var $intern= '';

    function __construct($initial= '') {
      $this->intern= $initial;
    }

    function length() {
      return strlen($this->intern);
    }

    function hashCode() {
      return DJBX33AHashImplementation::hashOf($this->intern);
    }

    function equals(&$cmp) {
      return is_a($cmp, 'String') && $this->intern == $cmp->intern;
    }

    function toString() {
      return $this->intern;
    }
  }
?>
