Fix problem with wing copy/paste and file read
Fixed case where the closest element from the lower bound was the last element (and not the end element).
Added ability to get the C0 interior edges from Code-Eli surfaces and add those coordinate directions to the vector of split directions for CFD Meshing.
Need Code-Eli version 0.3.3 for the C0 edge functionality.
Merge branch 'C0_Edge_Detection'

* C0_Edge_Detection:
  Need Code-Eli version 0.3.3 for the C0 edge functionality.
  Added ability to get the C0 interior edges from Code-Eli surfaces and add those coordinate directions to the vector of split directions for CFD Meshing.
  Fixed case where the closest element from the lower bound was the last element (and not the end element).
Include Code-Eli 0.3.3 which includes surface continuity reporting.
Fix incomplete BoxSource::Copy method
Add Geom::GetSurfPtr(i) and GetUWPt(i,u,w) to access specific surfaces.

Eventually plan to remove GetSurfPtr() and GetUWPt(u,w) as they assume
you always want to reference surface 0.

Place assert in GetSurfPtr to check for out of range index.
Track index pointing to main surface when making symm. copies of surfaces.
Add Geom::GetNumSymmCopies() to calculate symmetrical multiplicity.
Change name of Geom sourceVec member to m_MainSourceVec
Add current main surface index to CfdMeshMgr -- will be controlled by GUI
Add m_MainSurfIndx variable to BaseSource class
Add Geom::m_SurfSymmMap to perform lookup from main surface to symm copies.
Clean up unused GridDensity code.
Add m_SurfIndx to BaseSource
Remove redundant setting of CurrSourceID after AddSource
Copy m_MainSurfIndx and m_SurfIndx when copying sources.
Evaluate source on surface m_SurfIndx instead of surface 0.
Add m_SourceVec to contain complete set of sources (including symm copies).
