TC: Document common workflows that show function usage

[abafzal]

We need to write public documentation for several workflows that show users how to use functions in the Tamr Client.

Some ideas for workflows:

• Continuous mastering

• Continuous categorization

• Continuous schema mapping

• Continuous golden records

• Create mastering project

• Create categorization project

• Create schema mapping project

• Create golden record project (requires existing mastering project)

Thoughts are welcome.

Superseded by #449 . We can add additional workflows after continuous mastering is in.
