-- @param rotlist table<{axis: string, rad: number}> The list of rotations. Rotations will be processed in order. Each rotation is a table with a SINGLE axis as a string (x, y, z, -x, -y, or -z; the axis parameter), and an amount in radians to rotate by (the rad parameter).
|
|
-- @returns bool,string|table<{changed: number}> A success boolean (true == success; false == failure), followed by either an error message as a string if success == false or a table of statistics if success == true.

-- This is NOT NECESSARILY the number of nodes in the target region..... since not every node in the target region will support reorientation.
