- # - Explicit coordinates of nodes, e.g. [-1.5, 0.0, 3.1] or range( -100,200,10)
- # - Functions f(t) defining grid spacing at each point on grid axis. If there are
- # several functions, they must be accompanied by relative coordinates of
- # points dividing the whole shape into ranges where the functions apply; points
- # coodrinates should vary within (0.0, 1.0) range. Parameter \a t of the spacing
- # function f(t) varies from 0.0 to 1.0 witin a shape range.
- # Examples:
- # - "10.5" - defines a grid with a constant spacing
- # - [["1", "1+10*t", "11"] [0.1, 0.6]] - defines different spacing in 3 ranges.

- # a polyhedron of size less than hexSize/sizeThreshold is not created
- # @param UseExisting if ==true - searches for the existing hypothesis created with
- # the same parameters, else (default) - creates a new one
