The Monad type-class is a structure that represents
computations defined as sequences of steps: : a type with
a monad structure defines what it means to chain operations
together, or nest functions of that type.
for functional programming
To implement Monad:
The purpose of this type-class is to support the data-types in the
Monix library and it is considered a shim for a lawful type-class
to be supplied by libraries such as Cats or Scalaz or equivalent.
CREDITS: The type-class encoding has been inspired by the Scato
project by Aloïs Cochard and Scalaz 8
and the type has been extracted from Cats.
