Renamed Cat -> CatL, CatR -> Cat 
This way it is more obvious which of the categories is the fastest.
I might remove `CatR` later.

6657824470 CatR - optimised version of Cat 
This data structure is optimised for morphisms build with a right fold,
e.g. `(.)` and `foldr`.  The optimisations were visible with `-O1` and
`-O2`; with no optimisations (`-O0`), this data structure performs wors
than `Cat` or `ListTr`.

be5cfdc552 Optimise internal Queue 
Queue contains three 'ListTr', only the middle one, which holds reverse
values, should be forced to weak normal form.  Otherwise the queue will
not be as performant as designed.  A performance gain was measured.

Adding INLINE pragmas had a significant improvemnt in performance of the
queue.
