Die: the steel-rule die the drawing needs

POST /die runs the template with the values given and works out the steel-rule die it needs, as Make Die in ParametrIQ CAD does: the rule by kind (and how much of it is curved), the bridges and nicks, the holes, the sheet and how much of it the blanks use, and an estimate of the cost. This is the report; for the die's drawing, export the same template (see Making a Die).

The body is that of Drawing, and options: what the die has, and its costs. Lengths are in the drawing's units; anything left out takes its default.

Option
`margin`, `gripper`	The sheet round the blanks, each side (10), and more at its leading edge (12).
`bridges`, `bridgeWidth`, `bridgeSpacing`	Board left uncut along the rules, so the die holds together (on, 6, at most 75 apart).
`nicks`, `nickWidth`, `nickSpacing`	Tiny gaps in the cutting rule holding the blanks in the sheet (on, 0.5, at most 150 apart).
`registrationPins`, `airHoles`, `supportBars`, `stripping`	What else the die has: registration pin holes and air holes (on), support bars and stripping tools (off).
`automaticStripping`	With `stripping`: the tool that suits each piece of waste — pins for small waste, a perimeter stripper for curved, knives for the rest — rather than pins, knives and a stripper on every piece (off).
`lowerStrippingBoard`, `openingOversize`	The lower stripping board's openings, one under each piece of waste stripped (off), this much bigger than the waste all round (1).
`ejectionRubber`, `counterPlate`, `thickness`	Rubber by the cutting rule (on); counter-plate channels under the creases (on), for board of this thickness when the drawing has no `T` (0.5).
`cutRuleCost`, `creaseRuleCost`, `otherRuleCost`, `bridgeCost`, `holeCost`, `boardCost`, `baseCost`	The costs the estimate is made from: rule by the metre (4, 4, 6), each bridge (0.2) and hole (0.5), board by the square metre (60), and setting up (50).
`strippingBladeCost`, `openingCost`	The stripping tooling's costs: stripping blade (knives and strippers) by the metre (6), each opening in the lower stripping board (1).

usage is how much of the sheet the blanks use (0 to 1). warnings says what couldn't be done as asked.
