Detailed Description

/brief Port of https://github.com/nicolausYes/easing-functions Each function takes a given amount of time / progress in a normalised 0 - 1 range, and returns a value 0 - 1 based on the current position along a curve. Examples of each curve can be found at https://easings.net/en

Easing curves are generally useful for creating interesting motion in animated items such as UI objects. They can also be used to create tables of values where lookups are faster than repeatedly calling functions that use sin/cos/sqrt.
