FEniCS finite element basis evaluation library

Basix is a finite element definition and tabulation runtime library. Basix allows users to: * evaluate finite element basis functions and their derivatives at a set of points * access geometric and topological information about reference cells * apply push forward and pull back operations to map data between a reference cell and a physical cell * permute and transform DOFs to allow higher-order elements to be use on arbitrary meshes * interpolate into a finite element space and between finite element spaces Basix includes a range of built-in elements, and also allows the user to define their own custom elements. Basix is one of the components of FEniCSx, alongside UFL, FFCx, and DOLFINx.
