This submission implements lifting from a point cloud to a tangential complex, introduced in [1]

A Tangential (Delaunay) complex is a simplicial complex designed to reconstruct a $k$-dimensional manifold embedded in
$d$-dimensional Euclidean space. The input is a point sample coming from an unknown manifold. The running time depends only linearly on the extrinsic dimension $d$ and exponentially on the intrinsic dimension $k$.

Present implementation basically uses TCs implemented in Gudhi by Clément Jamin (image from there)
