Major Features
- `Vector` - new `CompositeResource` that uses `Mesh0D` and defines `vectors` at each point. This allows uploading of vector fields to steno3d.com.
- Currently, this only supports vector direction and not vector magnitude.
- OMF support - `Project` now has a class method `from_omf` which constructs a Steno3D project from an OMF file or `Project` created in the OMF API
Minor Changes
- `Mesh3DGrid` now supports geometries that are rotated and/or non-axis-aligned
- This is done by defining vector directions for each axis `U`, `V`, `W` (corresponding to `h1`, `h2`, `h3` respectively)
