Grayscale erosion and dilation: a very fast implementation.

We have optimized execution time of grayscale erosion and dilation. Our functions take advantage of MATLAB's decomposition of structuring
elements.

graydil(im,se) to perform dilation
im is the input 2D matrix (uin8, uint16, uint32 or double)
se the structuring element (logical or strel)

grayero(im,se) to perform erosion
im is the input 2D matrix (uin8, uint16, uint32 or double)
se the structuring element (logical or strel)

Memory management is not optimized ( our routines can generate
overflow memory error) but execution time is 2, 3, 4 or 5 times
smaller than MATLAB's one.
