**New features**
1. Structural damping analysis: Determine modal loss factors based on constituent properties
2. Blade root submodeling from in-house mesher.
**Improvements**
1. Solid in-house mesher and Abaqus solid model example, as well as to add some documentation and introduce the renaming of the pynumad.shell directory to pynumad.mesh_gen.
2. Cubit workflow: In the actual process of making beam and solid models with the Cubit workflow, many bugs and improvements were made to actually be able to use these models. Beforehand, only the geometry and some basic meshing was working. In particular, the solid model geometry generation was improved in that each volume uses adjacent volume spanwise splines. The material orientation was improved significantly in speed and accuracy.
3. yaml reader to base reference line off of the reference axis
4. PyPi Release
5. Updated data file structure and build config to allow data files to be included in normal installations/wheels.
