Verdict double star star

See merge request meshing/cubit!283

Fix for compiler warnings.  Distortion metric only works on the first six nodes of a tri7.  Ignoring the 7th node.

Implementing length/area calculations and include higher order nodes for 1D and 2D element types, such as:
bar3, tri6, tri7, triangle with center node (side of tetra8 element), quad5, quad8, quad9

Prevent collisions between constructors

Also add include directory in CMake Export file

Thanks for Tim Bender (LLNL) for finding this.

Fixed Verdict install locations for Cubit build.

Also fixed up our changes to work with his.

Additionally:
1) Add braces wherever possible for code clarity
2) Make all input coordinates const qualified
3) Remove not needed headers, and use c++ versions of needed headers
4) Fix typos
5) Comment out unused num_nodes parameters
6) Delete not implemented functions

Adding 'mean ratio' tet metric to Cubit.  Metric created and recommended by Jay Foulk to better detect elements that become elongated in high-deformation anlayses.  Compensates for 'normalized inradius' inability to detect these elements.
In Verdict (V_TetMetric.cpp), there was already a mean ratio metric for tet4s but it wasn't hooked up to anything, save some unit tests.  This metric is formulated differently and penalizes elements with high aspect ratio more than the previous implementation.  This metric now also can be computed on tet10 elements, computing the linear version on each subtet and returning the lowest.
The author of the previous metric was Danial Ibanez.  Jay Foulk with talk with him about this different implementation of it.  Soon we'll settle on which to go forward with.

Put package CMake files into a cmake directory.

This fixes a failing find_package() in alegranevada.

tet_radius_ratio() is used instead.
