QUADXY

Define an arbitrary, logical quad of points in 3D space with NDIM1 x NDIM2 number of nodes.
The four corners of the quad surface are defined in counter clockwise order ( the normal to the quad points is defined using the right hand rule and the order of the points).
The nodes can be connected using the createpts/brick/xyz command.

  EXAMPLES: quadxy / 3 5 /0. 0. 0./10. 0. 0./10. 20. 0./0. 20. 0.
createpts/brick/xyz/ 3 5 1 /1,0,0/connect
  Create a XY quad surface with 3 nodes in x direction and 5 nodes in y direction. See Example 1 image.
