Quadrupole Geometry Bug

[William Shields]

Holes appear in the quadrupole poles in the visualiser when running examples/features/components/quadTest.gmad, with the following in options.gmad (same dir.):

beampipeRadius = 5 * cm, outerDiameter = 20 * cm, magnetGeometryType="polescircular"/"polessquare"

[Laurie Nevay]

This was as expected with almost unrealistic geometry parameters. However, the pole geometry has since be reimplemented along with coils and now will always be solid and no holes will appear.
