T in the transformer names

[reubenharry]

Sequential -> SequentialT Traced -> TracedT Population -> PopulationT run[X] -> run[X]T

This helps Haskellers understand what is going on better.

### Tasks
- [ ] Sequential
- [ ] Traced
- [ ] Population
- [ ] Weighted
- [ ] Density
- [ ] Sampler
- [ ] run* functions

I'd love to help, but this does not make sense to me.

If you'd shared a doc on what is "transformer", how to find them in the code, I'd think of this as a task I could do.

Thanks.

Hi. Sure, I can clarify!

How familiar are you with Haskell? If not, it's actually ok for this one, because basically what I'm suggesting is just a renaming, as follows:

Everywhere "Sequential" appears in the code, we replace it with "SequentialT". So the type Sequential becomes SequentialT, the constructor Sequential also becomes SequentialT and runSequential becomes runSequentialT.

Similarly for Population and Traced.

I think search and replace would mostly work for this.

I'm ok with Haskell, not a brightest of minds but I'm learning:) there's only four of them? Ok, search and replace, on it.

grep -rnw -e 'Sequential' --include \*.hs

[aleeusgr]

find . -type f -exec sed -i 's/Sequential/SequentialT/g' {} \;

Hm, It breaks git repo...

find ./*.hs -type f -exec sed -i 's/Sequential/SequentialT/g' {} \; ??

[aleeusgr]

find . -name "*.hs" -type f -exec sed -i 's/<oldname>/<newname>/g' {} \;

also not to forget to rename .hs files and tests; update monad-bayes.cabal
