/**
 * A Timer class.  This represents an alert which the user wishes to activate at a point in time relative to the
 * current time.  This is different from requesting an alert at an absolute point in time.
 *
 * Timers may be basic, or named.  If named, they will use custom assets at the point of activation.
 *
 * Example of basic timer use:
 * "Alexa, set a timer for 10 seconds."
 * 10 seconds later : device will render a simple audio file, local to the device, to alert the user.
 *
 * Example of named timer use:
 * "Alexa, set an egg timer for 10 seconds"
 * 10 seconds later : Alexa will say something like "Your egg timer is complete".
