starting from the usual destriper, and out of its results starting the more comprehensive model to mitigate the atmospheric structures during the maps reconstruction.

@savaroskij check it out! It could be a really sensible theme for a doctorate proposal....

Thanks, I'm reading and trying to understand the binning function right now.

With the PR #9 the program is able to solve large linear problems with the PCG algorithm. The default preconditioner is the Jacobi preconditioner, that in genera represents a smart solution for this problems. In case of the atmosphere is not so easy. The stantards models and the jacoby preconditioner seem that don't work.

Btw, so far, the program can solve a problem with a maximum likelihood approach using the PCG. Let's start the fun in searching the correct model to mitigate the atmosphere.

Use step/by/step approach
