input - geometry of elements accepted by algorithm input. Used to define compatible algos of
different dimensions. Compatible algos have equal geometries in "input" and "output".
need-hyp - (optional) Boolean. Does the algo require a hypothesis or not. Default is "false".
- need-geom - (optional) Boolean. Can the algo work w/o geometry or not. Default is "true".
+ need-geom - (optional) [true, fasle, never]. Can the algo work w/o geometry or not.
+ Default is "true". "never" means that the algo can't work with geometry.
support-submeshes - (optional) Boolean. Does an multi-dimensional algo support sub-meshes.
Default is "false".
