Maze pyramid generator - easy style

This is based on Random maze generator, pure OpenSCAD. You may change the following parameters to generate a maze pyramid, different every time:

• square_block
• wall_thickness
• block_width

I call it as an easy style pyramid because it just linear_extrude the generated maze and intersection a cylinder with $fn=4. Easy but look not bad...XD

I also designed a Hex maze pyramid.
