gridz can now equal zero if only base is desired 

Setting gridz to 0 (or anything less than zero) will only generate the base pattern. This is useful in cases where you want to use those wonderful printable holes on other models.

`gridx` | {n>0\|n∈Z} | number of bases along the x-axis
`gridy` | {n>0\|n∈Z} | number of bases along the y-axis
`length` | {n>0\|n∈R} | size of the square bases in millimeters, default 42
`gridz` | {n>0\|n∈R} | height value (can be interpreted in various ways)
`gridz` | {n>=0\|n∈R} | height value (can be interpreted in various ways)
`gridz_define` | {0,1,2} | • (0) Unit height: `gridz` is the height in units (7mm increments). The stock bins have a unit height value of 2, 3, or 6. The overall height of the bin is `7*u + 3.8` millimeters, where the 3.8 is the height of the top lip. <br> • (1) Internal height: `gridz` is the height from the bottom of a compartment to the top of the tab in millimeters. This is effectively the maximum height of an object that can fit inside the bin. <br> • (2) External height: `gridz` is the overall height of the bin, from the base to the upper lip fillet. This is effectively how deep a drawer must be to fit the bin.
`enable_holes` | boolean | toggle holes for magnets and M3 screws on the base of the bin
`enable_hole_slit` | boolean | toggle the printable countersunk hole cut
