Description: The 'blocksdesign' package constructs nested block and 
    D-optimal factorial designs for any unstructured or factorial
    treatment model of any size. The nested block designs can have repeated 
    nesting down to any required depth of nesting with either a simple set 
    of nested blocks or a crossed row-and-column blocks design at each level
    of nesting. The block design at each level of nesting is optimized for
    D-efficiency within the blocks of each preceding set of 
    blocks. The block sizes in any  particular block classification are always
    as nearly equal as possible and never differ by more than a single plot. 
    Outputs include a table showing the allocation of 
    treatments to blocks, a plan layout showing the allocation of treatments
    within blocks (unstructured treatment designs only) the achieved
    D and A-efficiency factors for the block and treatment design 
    (factorial treatment designs only) and, where feasible,
    an A-efficiency upper bound for the block design (unstructured 
    treatment designs only).
