Implementation of 'Analysis Toolpak' Excel function IFS()

The IFS function checks whether one or more conditions are met and returns a value that corresponds to the first TRUE condition. IFS can take the place of multiple nested IF statements, and is much easier to read with multiple conditions.

Syntax
IFS(IFS([Something is True1, Value if True1, [Something is True2, Value if True2],…[Something is True127, Value if True127]))
