clangd setup

For anyone using clangd, for example with VSCode, you must generate a compile_commands.json file for features like autocomplete or symbol lookup to work. To do this we will use a tool called compiledb, which is a Python package. Assuming you have Python and pip installed, simply run pip install compiledb (pip3 on some Linux distributions) to install the package, and then run:

compiledb make

in the root of this repository. clangd should now function. You may need to close/re-open files or even your editor.
