// USAGE EXAMPLE
//-----------------------------------------------------------------------------
///Usage
///-----
// This section illustrates the intended use of this component.
//
///Example 1: Controlling Network Traffic Generation
///-------------------------------------------------
// Suppose that we want to send data over a network interface with the load
// spike limitations explained below:
//
//: o The long term average rate of resource usage (i.e., the sustained rate)
//: should not exceed 1024 bytes/s ('Rs').
//:
//: o The period over which to monitor the long term average rate (i.e., the
//: sustained-rate time-window) should be 0.5s ('Wp').
//:
//: o The peak resource usage (i.e., the peak rate) should not exceed 2048
//: bytes/s ('Rp').
//:
//: o The period over which to monitor the peak resource usage should be
//: 0.0625s (Wp).
//
// This is shown in Figure 2 below.
//..
// Fig. 2:
//
// ^ Rate (Units per second)

// | __ / \ / \__.

// --------------------------------------------->
// T (seconds)
//..
// Notice that we can understand the limitations imposed by the rate-limiter
// graphically as the maximum area above the respective lines, 'Rp' and 'Rs',
// that the usage curve to allowed to achieve. In the example above:
//
// o The area above the sustained rate 'Rs' (e.g., 'A1' or 'A2+B') should
// contain no more than 512 bytes.
//
// o The area above the peak rate 'Rp' should contain no more than 128 bytes.
//
// Further suppose that we have a function, 'sendData', that transmits a
// specified amount of data over that network:
