Curve interpolation node for NME

[PatrickRyanMS]

This node would be a conversion for any interpolation to a standard easing curve. The node would have a select box parameter to set which curve type will be used from the prepopulated list:

• [ ] easeInSine
• [ ] easeOutSine
• [ ] easeInOutSine
• [ ] easeInQuad
• [ ] easeOutQuad
• [ ] easeInOutQuad
• [ ] easeInCubic
• [ ] easeOutCubic
• [ ] easeInOutCubic
• [ ] easeInQuart
• [ ] easeOutQuart
• [ ] easeInOutQuart
• [ ] easeInQuint
• [ ] easeOutQuint
• [ ] easeInOutQuint
• [ ] easeInExpo
• [ ] easeOutExpo
• [ ] easeInOutExpo
• [ ] easeInCirc
• [ ] easeOutCirc
• [ ] easeInOutCirc

We should allow the standard input types (float, Vec2, Vec3, Vec4, Color3, Color4) as valid inputs and the output matches input.
