This node will insert knots at a particular parameter value(s).
An edit point will appear where you insert the knot. Also, the
number of spans and CVs in the curve will increase in the area where
the knot is inserted. You can insert up to "degree" knots at a
curve parameter that isn't already an edit point. eg. for a
degree three curve, you can insert up to 3 knots. The more
knots inserted at a parameter (default is 1), the more "pull"
the new CVs have. eg. if you insert 3 knots into a degree 3 curve,
one of the new CVs will have the curve passing directly through it.
Use this operation if you need more CVs in a local area of the curve.
Use this operation (or "hardenPoint") if you want to create a corner
in a curve.
This node is also useful if you have aligned an end of the curve at a
specific tangent and you want the ability to change the curve shape
near the end, while still maintaining the tangent. In this case,
you can insert a knot near (but not at) the end, then leave last two
CVs (which define the tangent) where they are, and modify any other
CV to change the curve shape.
