<h2 class="title">Introduction</h2>
<p class="para">
This class wraps around a hash containing strings, where the
values are integer numbers. Hashes are also available as
implementation of the ArrayAccess interface.
</p>
<p class="para">
Hashes can also be iterated over with foreach as the Iterator interface is
implemented as well. The order of which elements are returned in is not
guaranteed.
