Move all schema definitions under the global Schemas object

[brylie]

We are currently defining our schemas as global variables. This causes unnecessary clutter of our global namespace. Move all schema definitions to attributes of the global Schemas object.

Task

• Make list of all project schema definitions
• Move each schema definition to an attribute of the Schemas object
• Update the collection-schema attachment lines to use the global Schemas object/attribute
