/** Models a deadband object.
    This is a component that allows for some "play" in a control path, in the
    form of a dead zone, or deadband. The form of the deadband component
    specification is:

    @code
    <deadband name="Windup Trigger">
      <input> [-]property </input>
      <width> number </width>
      [<clipto>
        <min> {[-]property name | value} </min>
        <max> {[-]property name | value} </max>
      </clipto>]
      [<output> {property} </output>]
    </deadband>
    @endcode

    The width value is the total deadband region within which an input will
    produce no output. For example, say that the width value is 2.0. If the
    input is between -1.0 and +1.0, the output will be zero.
