Tests fail

[nickbrady]

test_t1.jl can run without error if

Gmsh.initialize() --> gmsh.initialize() Gmsh.finalize() --> gmsh.finalize()

test_t16.jl fails on line 9 gmsh.model.occ.addBox(0,0,0, 1,1,1, 1) with error: gmshModelOccAddBox returned non-zero error code: 1

this seems to happen for all of the gmsh.model.occ elements
