   4         roundedCube() v1.0.3 by robert@cosmicrealms.com from https://github.com/Sembiance/openscad-modules
   5         Allows you to round any edge of a cube
   6
   7         Usage
   8         =====
   9         Prototype: roundedCube(dim, r, x, y, z, xcorners, ycorners, zcorners, $fn)
  10         Arguments:
  11                 -      dim = Array of x,y,z numbers representing cube size
  12                 -        r = Radius of corners. Default: 1
  13                 -        x = Round the corners along the X axis of the cube. Default: false
  14                 -        y = Round the corners along the Y axis of the cube. Default: false
  15                 -        z = Round the corners along the Z axis of the cube. Default: true
  16                 - xcorners = Array of 4 booleans, one for each X side of the cube, if true then round that side. Default: [true, true, true, true]
  17                 - ycorners = Array of 4 booleans, one for each Y side of the cube, if true then round that side. Default: [true, true, true, true]
  18                 - zcorners = Array of 4 booleans, one for each Z side of the cube, if true then round that side. Default: [true, true, true, true]
  19                 -       rx = Radius of the x corners. Default: [r, r, r, r]
  20                 -       ry = Radius of the y corners. Default: [r, r, r, r]
  21                 -       rz = Radius of the z corners. Default: [r, r, r, r]
  22                 -   center = Whether to render the cube centered or not. Default: false
  23                 -      $fn = How smooth you want the rounding to be. Default: 128

  25         Change Log
  26         ==========
  27         2018-08-21: v1.0.3 - Added ability to set the radius of each corner individually with vectors: rx, ry, rz
  28         2017-05-15: v1.0.2 - Fixed bugs relating to rounding corners on the X axis
  29         2017-04-22: v1.0.1 - Added center option
  30         2017-01-04: v1.0.0 - Initial Release
  31
  32         Thanks to Sergio Vilches for the initial code inspiration
