    Book: fixed typo in dilate operator of Arithmetic
    
    Prior to this commit, the explanation of the dilate operator said
    "Erosion is simply a flipping of all background pixels..."
    
    "Erosion" should be "Dilation"
    
    With this commit, I have made this change.  I also improved the
    consistency in mentioning the background and foreground values
    between the erode and dilate operators.

 Erode the foreground pixels (with value @code{1}) of the input dataset (second

+Erosion is simply a flipping of all foreground pixels (with value @code{1}) to 
background (with value @code{0}) that are ``touching'' background pixels.
 ``Touching'' is defined by the connectivity.
 In effect, this carves off the outer borders of the foreground, making them 
thinner.
 This operator assumes a binary dataset (all pixels are @code{0} and @code{1}).
