Another small bugfix release and just a few micro-features.

Single structure NASTRAN files now include some starter executive control statements previously only output for assemblies.

CompGeom now reports area calculations for each subsurface (not just by tag).

Subsurfaces can now be re-ordered from the GUI.

Paths to control surface tag files are now correctly constructed in VSPAERO on Windows.

Degenerate edges that would lead to zero-node faces in NGon meshes are now cleaned up.

Warnings from Attribute Editor complaining about insufficient height have been silenced.

A fix in the previous version managed to mess up the normal vector direction for CompGeom and other mesh-type operations. This also has the effect of messing up surface orientation for VSPAERO.

FEA Beam properties were getting deleted and substituted for a default property -- even if they were used.

The FEA Mesh was visualized in FEA scale not VSP Model scale. While not the end of the world, it caused significant inconvenience. Mesh size parameters are still in FEA scale, but the resulting mesh is visualized in the model scale.

FEA mass calculations were often output with inappropriate precision and also without the context of the mass units. The number formatting has been improved and units added to the console output of mass property totals.

So, not a whole lot here -- but it is all good stuff. These bugs were hitting
users, so update to avoid these issues.

Features:
 - Single structure NASTRAN file now includes executive control deck
 - Detailed subsurface area outputs from CompGeom
 - SubSurfaces can now be re-ordered

Bug Fixes:
 - VSPAERO control surface tag file paths correctly constructed
 - Degenerate edges cleaned up in NGon files
 - Attribute Editor height warnings silenced
 - Normal vector directions for CompGeom and other meshes
 - FEA Beam properties getting deleted
 - FEA Mesh visualization scale
 - FEA Mass properties precision and units in output

Thanks for the bug fixes! The one for VSPAERO control surface tag file paths works!
