Allow Documentation for Lists and Maps

[norwoodj]

We should allow non-empty lists and maps to be included in the values table with descriptions. This issue asks that we implement the following behavior for values table generation:

• Only leaf nodes (empty lists, empty objects, strings, ints, and floats) are automatically documented
• If a list or object has a comment with a description, document it as a value, as you have done here. The default field for lists and objects in this case should be a jsonified string of the field
• Documenting a list or object in the above fashion stops the automatic documentation of contained fields, that is, they will not be added to the values table. However, if a contained field has a description comment on it, then it will then be included.

An example:

exampleObjectNoDescriptions:
  key: value

exampleListNoDescriptions:
  - key: value

# exampleObjectDescription -- this object will be documented
exampleObjectDescription:
  keyNoDescription: value

  # exampleObjectDescription.keyWithDescription -- this object key will be documented
  keyWithDescription: value

# exampleListDescription -- this list will be documented
exampleListDescription:
  - keyNoDesciption: value

  # exampleListDescription[1].keyWithDescription -- this list item key will be documented
  - keyWithDescription: value

  # exampleListDescription[2] -- this list item will be documented
  - listItemWithDescription: value

Produces

Key	Type	Default	Description
exampleObjectNoDescriptions.key	string	"value"
exampleListNoDesciptions[0].key	string	"value"
exampleObjectDescription	object	{"keyNoDescription": "value", "keyWithDescription": "value"}	this object will be documented
exampleObjectDescription.keyWithDescription	string	"value"	this object key will be documented
exampleListDescription	list	[{"keyNoDescription": "value"}, {"keyWithDescription": "value"}, {"listItemWithDescription": "value"}]	this list will be documented
exampleListDescription[1].keyWithDescription	string	"value"	this list item key will be documented
exampleListDescription[2]	object	{"listItemWithDescription": "value"}	this list item will be documented

Note how exampleListDescription.keyNoDesciption and exampleObjectDescription.keyNoDescription aren't documented because the containing object and list themselves have description comments, but the other contained keys are documented because they do have description comments.
