Document how to make use of common data types in different contexts

• Show if fields
• code blocks
• DOCX file
• PDF attachment (mako tags)

Maybe this should go on the legal tech class website and be a cross reference there

Docassemble's documentation isn't so clear about what the different datatypes end up creating in Python land.

1. datatype: checkboxes makes a DADict where each option is either True or False. Convenience methods can help you test the values.
2. datatype: radio makes a string.

Should document datatype: yesnomaybe and properly testing it with show if logic
