Issue I415 [gui,pe,enhancement,resolved] Allow PE/Contour views of PA's with no electrode points. Prior to 8.0.4-TEST5, SIMION refused to show PE views or auto contours of PA's containing no electrode points (even if the non-electrode points have meaningful potentials, such as due to cropping - Issue I313). This restriction is now removed. Affects 7.0 and 8.0.x. Resolved in 8.0.4-TEST5 and 8.0.4-TEST9.
