//=================================================================
// This class deals with resetting a target.
// The ctor accepts the "reset string" this is something like
//    expect($T05,#) 3(off(ginga:5000,a1) delay(2000) on(,..com2,38400))
// and is parsed to generate the commands to reset the target.
// The syntax is:
//    resetstring :== [directive | <integer>(resetstring)] * 
//    directive   :== id(arg[,arg]*)
//    directive   :== port | action | delay | expect
//
// The <integer>(string) syntax repeats argument its until reset is achieved.
// Each directive is given by example below:
// expect: 
//   Expected string(s).            e.g. expect(str1,str2,...).
//   Arguments:
//     The string(s) expected to be output by a target after reset.
//     *all* supplied strings must be present *in order* in the reset string for a reset to be recognized as valid.
// port:
//   Provide port information to apply to all subsequent off|on|on_off|off_on actions until overwritten.
//   e.g. port(com1,38400,1000)
//   Arguments:
//     0. Port
//     1. Baud
//     2. Read timeout
//   These have the meanings described under off|on|on_off|off_on.
// off|on|on_off|off_on:
//   Request a reset host to perform a "power cycle" (or its logical equivalent - 
//   the meanings of "off" and "on" may depend on the reset host)
//   e.g. off_on(ginga:500,A4,com1,38400,10000,1000)
//   Arguments:
//     0. Reset host:port
//     1. Control string (meaning known to the reset host)
//     2. Port (from which to read startup output)
//     3. Baud for the above
//     4. Read timeout
//     5. Delay (between off and on or vice versa)
// delay:
//   Delay for a given time right now.      
//   e.g. delay(1000)
//   Arguments:
//     0. msec to delay
