24    Defines maxdim with two arguments: two 2D spaces
25    BLOCK START - maxdim, returns the discrete convex hull of the two spaces
26    Declares a dimension (width and height pair)
27    Initializes width to the larger of the two input dimensions
28    Initializes height to the larger of the two input dimensions
29    Returns the computed dimension
30    BLOCK END - maxdim
