#219 Peak picking error in flipped views of 3D data

[Brian Smith]

Picking a peak in a 3D experiment can get the indirect dimensions confused in assign 3.0.b2.

For a correctly displayed 3D HNCACO that assign opens with H,N planes shown, peaks picked in the default view are correctly placed, but attempting to pick a peak in an H,C,z=N view created using View->Current->Flip YZ axis apparently causes no peak to be created. In fact the new peak is created, but with the 13C coordinate set to the 15N shift and vice versa.
