// Now for the arguments to this metaball() module or function....
// Arguments:
// funcs = a 1-D list of transform and function pairs in the form `[trans0, func0, trans1, func1, ...]`, with one pair for each metaball. The transform should be at least `move([x,y,z])` to specify the location of the metaball center, but you can also include rotations with the translation, such as `move([x,y,z])*rot([ax,ay,az])`. You can multiply together any of BOSL2's affine operations like {{xrot()}}, {{scale()}}, and {{skew()}}. This is useful for orienting non-spherical metaballs. The priority order of the transforms is right to left, that is, `move([4,5,6])*rot([45,0,90])` does the rotation first, and then the move, similar to normal OpenSCAD syntax `translate([4,5,6]) rotate([45,0,90]) children()`.

// isovalue = A scalar value specifying the isosurface value of the metaballs.
// bounding_box = A pair of 3D points `[[xmin,ymin,zmin], [xmax,ymax,zmax]]`, specifying the minimum and maximum box corner coordinates. The voxels needn't fit perfectly inside the bounding box.
// voxel_size = The size (scalar) of the voxel cube that determines the resolution of the metaball surface. **Start with a larger size for experimenting, and refine it gradually.** A small voxel size can significantly slow down processing time, especially with a large `bounding_box`.
