Input Definitions
Inputs Needed to Call the Tee Function
origin - a 3*1 matrix with x,y,z positions corresponding to the point where the tee will be drawn.
R1 - the inner radius of the main pipe.
R2 - the outer radius of the main pipe.
R3 - the outer radius of the sockets of the tee.
L - the length of the skinnier pipes of the tee.
H - the length (or depth) of the sockets of the tee.

Technical Program Outline
viewtop - sets the workspace so that the user is viewing the object from the top.
zoom win - zooms the workspace to a smaller focus area
cylinder1 - creates a cylinder with length 'L' that comes out of the page.
cylinder2 - creates a cylinder with length 'L/2'.
union1 - unions the two cylinders.
cylinder3 - creates a cylinder with length 'L'.
cylinder4 - creates a cylinder with length 'L/2'.
subtract1 - subtracts the portion of cylinder2 and cylinder4 that are inside the cylinders creating a hollow pipe out of cylinder2 and cylinder4.
subtract2 - subtracts cylinder 3 from cylinder 1 creating a hollow pipe coming out of the page.
tee viewed from viewfront
cylinder5 - creates a cylinder with a depth 'H' and radius 'R3' into the page.
cylinder6 - creates a cylinder with a depth 'H' and radius 'R1' into the page.
subtract3 - subtracts cylinder 6 from cylinder 5 creating a hollow pipe with length 'H'.
viewfront - sets the workspace so that the user is viewing the object from the front.
zoom win1 - zooms the workspace to a focus area
mirror1 - mirrors the bottom pipe 90 degrees clockwise.
mirror2 - mirrors the bottom pipe 180 degrees.
bigunion1 - joins all four pipes.
