csgtol-keyword becomes argument

[lmh91]

Closes #207

Okay, I found out what the problem was. The compiler does not like keywords...

So the code

using BenchmarkTools
using SolidStateDetectors
sim = Simulation(SSD_examples[:InvertedCoax]);
g = sim.detector.contacts[2].geometry; # consists out of 6 primitives
pt = CartesianPoint{Float32}(100, 0, 0); #outside
in(pt, g); @btime in($pt, $g); 

results in
