| Summary : Semigroupoids: Category sans id

Description :
Provides a wide array of (semi)groupoids and operations for working with them.
A \'Semigroupoid\' is a \'Category\' without the requirement of identity arrows for
every object in the category.
A \'Category\' is any \'Semigroupoid\' for which the Yoneda lemma holds.
When working with comonads you often have the \'< *>\' portion of an
\'Applicative\', but not the \'pure\'. This was captured in Uustalu and Vene\'s
\"Essence of Dataflow Programming\" in the form of the \'ComonadZip\' class in the
days before \'Applicative\'. Apply provides a weaker invariant, but for the
comonads used for data flow programming (found in the streams package), this
invariant is preserved. Applicative function composition forms a semigroupoid.
