removed Luxor from the docs project and fixed the Vis.drawhexcells to…

… support the native julia way of displaying a drawing by using the Luxor.preview function which will return a drawing that will be drawn according to the correct context. (#245)

 There is also a function to compute the n rings of a cell x, i.e., the cells which can be reached by taking no more than n steps along the lattice from x:
 
 ```@example 
 using OpticSim
 Vis.drawhexcells(50,Repeat.neighbors(Repeat.HexBasis1,(0,0),2))
-HTML(Vis.drawhexcells(50,Repeat.neighbors(Repeat.HexBasis1,(0,0),2), format=:svg)) #hide

 You can also draw all the cells contained within an n ring:
 
 ```@example 
 using OpticSim
 Vis.drawhexcells(50,Repeat.region(Repeat.HexBasis1,(0,0),2))
