Build wheel for pyodide to be used in GUI

After sourcing emsdk environment, run the following:

pyodide build && python -m build --sdist

Install the package with pip

The package is not available on PyPA yet, but will be in the future. Till then, the installation process is the following:

• Download this project. For instance using git: git clone [e-mail]:gabrielfougeron/choreo.git
• Open the directory: cd choreo
• Build and install using pip: pip install .

Power up the GUI solver with the CLI backend

Using clang or gcc as a C compiler, the single-threaded CLI solver is about 3 times faster that the wasm in-browser GUI solver. In addition, several independent single-threaded solvers can be launched simultaneously using a single command.

To use the CLI backend, follow these steps:

• Install the package
• In the GUI, define a workspace folder under Play => Workspace => Setup Workspace
• Every time the workspace is reloaded under Play => Workspace => Reload Workspace or every time a new initial state is generated in the GUI, a new configuration file choreo_config.json is written to disk.
• In the command line, run the installed script as choreo_CLI_search -f /path/to/workspace/folder/
