function sidePositions = getBlockSidePositions(blocks, side)
    % GETBLOCKSIDEPOSITIONS Find the *unique* block positions for a given side
    % of a set of blocks.
    %
    % Inputs:
    %   blocks          Cell array of the full names of block(s). If a cell
    %                   array is given for one of the block names, the first
    %                   element is used.
    %
    %   side            Number respesenting the following:
    %                       1 - Left
    %                       2 - Top
    %                       3 - Right
    %                       4 - Bottom
    %                       5 - Midpoint between results of 1 and 3
    %                       6 - Midpoint between results of 2 and 4
