Parametric Dovetail Joint

This thing creates a customizable dovetail joint when can be used to securely joint two different pieces.

The definitions of the parameters:

Pin Depth : the depth of the Pin from the start of the chamfer to the widest part of the pin
Pin Width : the width of the widest part of the pin
Tail Height : the height of the tail block
Pin Width Fraction : 1 minus the ratio of the narrowest part of the pin (start of the chamfers) to the widest part. A value of 0.4 would result in the width of the narrowest part of the pin being 60% of the widest part
Pin Height Fraction : the ratio of the height of the pin to the height of the tail block. A value of 0.8 would result in the pin being 80% of the height of the tail block.
Overhang Depth : additional depth added to the narrow end of the pin and the back of the block
Overhang Width : additional width added to the tail block on each side of the pin chamfers
Fit Tolerance : the absolute value of the total amount to shrink the wid
