The documentation does not explain how to use ClimaTimeSteppers

[Sbozzolo]

As the title suggests, there is no documentation in https://clima.github.io/ClimaTimeSteppers.jl/dev/ on how to use ClimaTimeSteppers.jl.

It is also hard to find a simple example among the tests.

Here are some of the things I would have never figured out by myself (not for lack of trying):

• When using ClimaCore, Y has to be a FieldVector (cannot be a Field)
• What is Wfact
• What is Wfact_t and the relationship with Wfact
• And there is lots and lots of things that I still haven't figured out (what is jac_prototype?)

ClimaTimeSteppers is a foundational package. I think that the fact that the only place where information about this package is the brains of a restricted number of individuals should be fixed as soon as possible.

Even after having used this package for a while, I am still struggling. The package does not even come with one example on how to set up a simple scalar problem (in particular, with an implicit component).
