Examples of use?

[inklesspen]

Hi, I think slurry is good for my use case, but I cannot tell for sure, because there are not enough examples of using the various parts of the library in combination.

I would particularly like to know:

• the best way to have a pipeline take input from a Trio memory channel
• the best way to have a pipeline tap output into a Trio memory channel
• how to enable/disable sections of a pipeline on the fly
