Summary

0000795: IMPLEMENTED: fitting irregular data by penalized bicubic spline

Description

Implemented two fitting algorithms:
* BlockLLS, efficient direct sparse solver which supports nonlinearity penalty and works on grids with up to 512x512 nodes.
* FastDDM, large-scale solver intended for problems with huge amounts of points (supports grids with up to 10000x10000 nodes)

Both solvers support parallelism, although only FastDDM shows nearly-linear scaling.
