v0.0.1-alpha

This is a technology preview for the new GaitSym5. It demonstrates a number of cool new features, and whilst by no means complete, I am starting to use what's currently there so it is worth sharing.

Here is what is new:

1. ODE, PhysX and MuJoCo physics engine support
2. New three.cpp rendering engine (shadows, lights, transparency)
3. OpenSim Moco compatible export

These features only work for a subset of models currently but will eventually become more complete. In the pipeline are some new wrapping modes, and some more visualisation enhancements., and the new physics engines offer some useful enhancements too.

The current release includes all the main dependencies and it should just compile with QtCreator. PhysX is not currently supported on the Mac (although it can be persuaded to work I believe), and I have only tested the GUI on Windows (the command line version runs happily on Linux). The binary is a simple Windows installer created with CQtDeployer. The model file format has changed slightly from GaitSym2019 since it needs to define the physics engine and the optimiser format has changed too. GaitSym2019 should still be used for serious work because GaitSym5 is changing quickly, however this is where the new features will happen.
