===== Functies =====
  * ''bal = ui_scalar('Bal/diameter (mm)', 239, 0, 600)'' -> 1e veld is text/label, default waarde, minimum waarde, max waarde)
  * ''emit(object)'' -> tekenen van Object 'dhoek'
  * ''difference(objetA,objectB)'' -> wegsnijden van objecte adv object.
  * ''emit(translate(0,0,0)*ring)'' -> op een specifieke plaats tekenen van het object
  * ''print("Here is a string" .. ' concatenated with ' .. 2 .. ' other strings.')'' -> om text te printen/tussentijdse feedback
  * 
===== Voorbeelden =====
==== Driehoek ====
<code>
L = 160 
H = 200 

D = 83/2   
Db = D + 4 

dikte = 20 
-- weergeven variable waarde
v1 = ui_scalar('.A', 0, 0, 300)
v2 = ui_scalar('.B', 0, 0, 300)
v3 = ui_scalar('.C', 0, 0, 300)
v4 = ui_scalar('.D', L, 0, 160)
v5 = ui_scalar('.E', H, 0, 200)
v6 = ui_scalar('.F', (L/2), 0, 80)

triangle = { v(v1,v2), v(v3,v4), v(v5,v6) }

dir = v(0,0,dikte)

dhoek = linear_extrude(dir, triangle)
emit(dhoek)
</code>
==== Cilinder ====
<code>

hoogte = 40

buitenring = cylinder(160,hoogte)
binnenring = cylinder(100,hoogte)

ring = difference(buitenring,binnenring)

emit(ring)
</code>

==== Binnen verval ====
<code>
bringbuitenrand = 92 /2
bringbinnenrand = 35 /2
kegellengte = 30
bringdikte = 50




-- DEEL 1 (Platte ring)
--*******************************************
bevestigingsring = difference(cylinder(bringbuitenrand,bringdikte),
           cylinder(bringbinnenrand,bringdikte)
          )

--emit(bevestigingsring)

-- DEEL 2 (kegel)
--*******************************************
kegel = cone(bringbuitenrand, bringbinnenrand, kegellengte)


--emit(kegel)

-- DEEL 3 (Ring - kegel)
--*******************************************
