@class PKScientificNumberState
@brief A <tt>PKScientificNumberState</tt> object returns a number from a reader.
@details <p>This state's idea of a number expands on its superclass, allowing an 'e' followed by an integer to represent 10 to the indicated power. For example, this state will recognize <tt>1e2</tt> as equaling <tt>100</tt>.</p>
<p>This class exists primarily to show how to introduce a new tokenizing state.</p>
