-- This creates an array which stores all the bodyparts, it's size is depending on the global values pDim and sSParts.
-- The first parameter i, tells us how many parts fit into the array, so it iterates from 1 to sSParts, each part has his own value i.
-- The second, third and fourth parameters are the relative coordinates of the part, you have to start at (0,0,0) and be sure you fill the array into the right direction. A short example: your part is 2 griddimensions long and you place it in the game, that the relative coordinate point is at (0,0,0) and the part lies in the positive z-axis, then you have to use the coordinate point (0,0,1).
-- The fifth parameter is an array with size 4, at index=0, you have to set 1 if your part covers the gridpoint at (x,y,z), otherwise 0. At index=1,2,3 you define the possible connection directions (1 for x, 2 for y and 3 for z), be sure to use the notation from above (0, "+-", "+", "-").
