v1.4.0
Added the following features:
- An argument for hyper-4 functions that, when set to true, has them use the linear approximation even for bases <= 10, ensuring consistent behavior in situations where consistent behavior is needed (such as in an incremental game that uses tetration)
- Support for XFY format in fromString
- mod/modular function
- Super roots of arbitrary length (but only for the linear approximation, as super roots don't really work without a consistent definition of tetration)
