// Description:
// Makes a very simple screw model, useful for making screwholes.
// Usage:
// screw(screwsize, screwlen, headsize, headlen, [countersunk], [orient], [anchor])
// screw(screwsize, screwlen, headsize, headlen, [orient], [anchor])
// Arguments:
// screwsize = diameter of threaded part of screw.
// screwlen = length of threaded part of screw.
// headsize = diameter of the screw head.
// headlen = length of the screw head.
// countersunk = If true, center from cap's top instead of it's bottom.
// orient = Orientation of the screw. Use the `ORIENT_` constants from `constants.scad`. Default: `ORIENT_Z`.
// anchor = Alignment of the screw. Use the constants from `constants.scad` or `"sunken"`, or `"base"`. Default: `"base"`.
// anchor = Translate so anchor point is at origin (0,0,0). See [anchor](attachments#anchor). Default: `CENTER`
// spin = Rotate this many degrees around the Z axis after anchor. See [spin](attachments#spin). Default: `0`
// orient = Vector to rotate top towards, after spin. See [orient](attachments#orient). Default: `UP`
// Extra Anchors:
// "base" = At the base of the head.
// "countersunk" = At the head height that would be just barely exposed when countersunk.
// Examples:
// screw(screwsize=3,screwlen=10,headsize=6,headlen=3,countersunk=true);
// screw(screwsize=3,screwlen=10,headsize=6,headlen=3, anchor="countersunk");
// screw(screwsize=3,screwlen=10,headsize=6,headlen=3, anchor="base");
// Example(FlatSpin): Standard Anchors
// screw(screwsize=3,screwlen=10,headsize=6,headlen=3)
