Fixed some flaws in the original API, deprecated various methods, and introduced some new features.
- Now attribute arrays are accessed via TAttributesRef or TAttributesView (and corresponding const versions). These value types hold references to attribute arrays, and individual elements can be accessed by their element ID and attribute index. Using a value type is safer than the previous method which required assignment to a const-ref (and not doing so would take a temporary copy of the attribute array).
- The attribute set has been totally flattened, so all attributes of different types are added to the same container. This greatly improves compile times, prevents attributes from being created with the same name but different types, and permits the view feature.
- The class hierarchy has changed to have generic base classes where possible with no particular ElementID type. This reduces the code footprint by no longer generating nearly identical copies of templated methods.
- A TAttributesView allows the user to access an attribute array by the type of their choosing, regardless of its actual type. For example, the Normal attribute may be registered with type FPackedVector, but accessed as if it was an FVector. This allows us to move away from very strong typing, and instead transparently store attributes of a more efficient size, while the user is not affected.
- A transient attribute flag has been added, to denote that a particular attribute should not be saved.

- Refactor to put UStaticMesh Mesh Descriptions in a separate object which is not loaded by default, but which can be requested when needed. This needs to be kept in sync with the number of SourceModel LODs.
- Various refactors to import/building.
- Changed UMeshDescription to FMeshDescription, and made its preferred semantics pass-by-reference rather than by pointer.
- Deprecated UMeshDescription.
