Various utility functions for the `Either`

type
## Types

stripLeft :: `a` ⊕ `b` -> Maybe `a`
stripRight :: `a1` ⊕ `a2` -> Maybe `a2`
stripEither :: `a` ⊕ `a` -> `a`
filterLeft :: [`b1` ⊕ `b2`] -> [`b1`]
filterRight :: [`a` ⊕ `b`] -> [`b`]
isLeft :: `a` ⊕ `b` -> Bool
isRight :: `a` ⊕ `b` -> Bool
mapEither :: (`t1` -> `a`) -> (`t2` -> `b`) -> `t1` ⊕ `t2` -> `a` ⊕ `b`
swapEither :: `b` ⊕ `a` -> `a` ⊕ `b`
splitEitherList :: [`a1` ⊕ `a2`] -> ([`a1`], [`a2`])
fromLeft :: `a` ⊕ `b` -> `a`
fromRight :: `a` ⊕ `b` -> `b`

## Description

These are various common utility functions for the Either type.
Note that in many places in the documentation we write
`a+b`

or `a⊕b`

as an abbreviation of `Either a b`

.
