Rush hour - Limit all dimmers to 70%

For this example a for iteration must be used to verify the level of all dimmers and in the case the level is greater than 70, turn them down to 70. ipairs(arr) is an array of the type (index,array)

-- Rush hour example code:
function(event, engine)
   -- Get all the dimmers
   local dimmers = engine.query("*/*/DIMMER/*")
   -- Iterate through them
   for i, v in ipairs(dimmers) do 
      -- If their level is > 70...
      if tonumber(v.get("LEVEL")) > 70 then
         -- Set it to 70 .. "/" .. .. "/DIMMER/" .. .. "/SET?LEVEL=70")
