this function will use the minimum and the maximum values found in the array, to normalize everything between 0 and 1

Array::normalize = ->
 return @ unless @length
 min = max = @[0]
 for i in @
 min = i if i < min
 max = i if i > max
 return @ unless max - min
 for i in [0...@length]
 @[i] = (@[i] - min) / (max - min)
 @

example:

console.log [300,400,150,230,200].normalize()
[ 0.6, 1, 0, 0.32, 0.2 ]
