<!-- Attributes of hypotheses/algorithms:

     type - string identifier of a hyp.
     label-id - hypothesis type name in Create Mesh dialog.
     icon-id - not used.
     group-id - (optional) integer ID of a group the hyp belongs to in Create Mesh dialog;
                by default the hyp is in the last group.
     priority - (optional) priority within the group; by default the hyp is last in group.
     dim - dimension; defines a tab page in Create Mesh dialog.
     context - (optional) allowed context: [LOCAL, GLOBAL, ANY(default)]. LOCAL - the hyp 
               can be only local (on sub-mesh). GLOBAL - the hyp can be only GLOBAL (on mesh).
     auxiliary - (optional) Boolean. Is additional hyp or not. Default is "false".
     hypos - list of types of compatible hyps of the algorithm.
     opt-hypos = (optional) list of types of compatible ADDITIONAL hyps of the algorithm.
     output - geometry of elements generated by the algo. Used to define compatible algos of
              different dimensions. Compatible algos have equal geometries in "input" and "output".
     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) [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".
