    Virtual Thermostat for 3 Speed Ceiling Fan Control

    This smartapp provides automatic control of Low, Medium, High speeds of a ceiling fan using 
    any temperature sensor with optional motion override. 
    It requires two hardware devices; any temperature sensor and a dimmer type smart fan controller
    such as the GE 12730 or Leviton VRF01-1LX
    
   Change Log
+  2016-06-30 added dynamic temperature display on temperature setpoint input text
   2016-06-28 x.1 version update
   			added submitOnChange for motion so to skip minutes input next if no motion selected
  			changed order of inputs for better logic flow

   2016-5-4b cleaned debug logs, removed heat-cool selection, removed multiple stages
   2016-5-3  fixed error on not shutting down, huge shout out to my bro Stephen Coffing in the logic formation 
   
-  Known Behavior from original Virtual Thermostat code
-  -(fixed) when SP is updated, temp control isn't evaluated immediately, an event must trigger like change in temp, motion
-  - if load is previously running when smartapp is loaded, it isn't evaluated immediately to turn off when SP>CT
+  I modified the SmartThngs original Virtual Thermostat code which is buggy. Known issues
+  -[Fixed] when SP is updated, temp control isn't evaluated immediately, an event must trigger like change in temp, motion
+  - if load is previously running when smartapp is loaded, it isn't evaluated immediately to turn off when SetPt>CurrTemp
+  - temperature control is not evaluated when making a mode change, have to wait for something to change like temp
