Docs not clear on defining attrs for custom fields

[mfreeman-xtivia]

I have read and then re-read the FormBuilder docs and for the life of me its not obvious.

If i am building a new custom control Foo, and it needs to support user-editable attributes A, B, and C, how and where do I define that for my custom control?

There is a new option named defaultAttrs. Docs updated in docs/formBuilder/overview.md
