VecMem Beta 0.2.0

Release containing a lot of improvements since v0.1.0. Now providing enough of a core functionality for acts-project/traccc's first use cases.

VecMem Alpha 0.1.0

This is the first numbered release of the project. Creating a snapshot of the code before some upcoming re-organisations/updates.

The code can already do a lot of clever things in this version, but this is absolutely considered a very early version of the code.
