<p>This is just an experiment to test my mental understanding of Python. It should not be used in any code as is violates the design principle that floats are to be immutable. The code also abuses <code>ctypes</code> and an understanding of how <code>floats</code> are currently arranged in memory. <code>set_float</code> is not guaranteed to work properly on any system, and may fail to work in the future if the data's arrangement changes.</p>

Revision 2.
</p>
<p>Provides a data structure for a queue of integers whose get() method returns the median element. The interface is similar to the standard Queue module, with an added method top() to retrieve the median without removing it.</p>

</p>
<p>Implements a data structure for sets of natural numbers, represented by a single integer. The interface is similar to the built-in structure 'set'.</p>
