*	ell_relax -> ell_grid_solve	Anton Khirnov	2019-01-26
\| \| \| \| \|	Generalize the API to allow for multiple solver types. This is done in preparation for the exact linear system inversion solver.
*	mg2d: factor out the boundary condition-related API	Anton Khirnov	2019-01-25
\|
*	Stop duplicating some constants between ell_relax and mg2d.	Anton Khirnov	2019-01-25
\|
*	mg2d: split the constant definitions into their own header	Anton Khirnov	2019-01-25
\| \| \| \|	This will allow sharing them with ell_relax.
*	mg2d: log the convergence factors after relax/correct	Anton Khirnov	2019-01-22
\|
*	mg2d: fix typo	Anton Khirnov	2019-01-21
\| \| \| \| \|	Do nb_relax_post steps in the post-correct relaxation phase, not nb_relax_pre.
*	mg2d: failer earlier when relaxation does not converge	Anton Khirnov	2019-01-21
\|
*	mg2d: check and propagate the error from mg_solve_subgrid()	Anton Khirnov	2019-01-21
\|
*	mg2d: factor out the relaxation step call	Anton Khirnov	2019-01-16
\|
*	mg2d: add a context variable to control the log level	Anton Khirnov	2019-01-16
\| \| \| \| \| \|	Simpler to use than overriding the log callback. API bump.
*	mg2d: add a function for getting maximum supported fd_stencil	Anton Khirnov	2019-01-16
\| \| \| \| \| \| \|	This is needed for the caller to know the number of boundary zones that can be filled. API bump.
*	ell_relax: compute the residual norm in residual_calc()	Anton Khirnov	2019-01-13
\| \| \| \|	It is cheap and avoids an extra step in mg2d.
*	mg2d: make the cfl factor runtime-configurable	Anton Khirnov	2019-01-13
\|
*	mg2d: ignore padding values in findmax()	Anton Khirnov	2019-01-09
\|
*	mg2d: remove a mistakenly committed hunk.	Anton Khirnov	2018-12-28
\|
*	mg2d: factor out restriction/prolongation calls	Anton Khirnov	2018-12-28
\| \| \| \| \|	Also generalize the check for full interpolation vs special-cased restrict/prolong functions.
*	mg2d: print the overhead time in stats	Anton Khirnov	2018-12-28
\|
*	mg2d: do not select the first coarser level too close to the finest one	Anton Khirnov	2018-12-28
\|
*	mg2d: simplify and speed up prolongation	Anton Khirnov	2018-12-27
\|
*	Add threading support through libthreadpool.	Anton Khirnov	2018-12-27
\|
*	mg2d: initialize the solver stepsize before it is used	Anton Khirnov	2018-12-27
\|
*	Add CPU feature detection.	Anton Khirnov	2018-12-27
\| \| \| \|	Will be used for dynamically dispatching future asm functions.
*	mg2d: define log levels	Anton Khirnov	2018-12-06
\|
*	mg2d: enforce a minimum domain size of 3 points	Anton Khirnov	2018-12-05
\|
*	mg2d: check the domain size validity earlier	Anton Khirnov	2018-12-05
\|
*	Finish support for 4th order accuracy.	Anton Khirnov	2018-11-28
\| \| \| \|	ABI and API break.
*	Add a function to measure timings for benchmarking.	Anton Khirnov	2018-09-26
\|
*	mg2d: fix boundary values allocation	Anton Khirnov	2018-08-07
\|
*	mg2d: use injection for diff coeffs restriction	Anton Khirnov	2018-08-07
\|
*	mg2d: actually initialize u to zero as documented	Anton Khirnov	2018-08-07
\|
*	Add support for non-power-of-2 sized grids.	Anton Khirnov	2018-08-01
\|
*	Implement the multigrid scheme.	Anton Khirnov	2018-08-01
