See also / sc-related

[jamesb93]

Currently the see-also and sc-related don't do all the things we'd like to.

1. sc-related should talk to Guides/FluCoMa, Guides/FluidDecomposition in all instances (probably)
2. Other objects for max, fluid.pitch~ -> somefundamentalpitchtrackernativeobject~

[jamesb93]

max-related, pd-related should be added to YAML so we can reference out to native objects. Python will need to be updated to understand this.

I've contributed a series of Max see-also's in this PR: #155

Just needs SC and PD
