Support for Adobe Client Datalayer

## Document Adobe Client Datalayer Usage with Alloy

Background: The [Adobe Client Datalayer](https://github.com/adobe/adobe-client-data-layer) is another open source project at Adobe to provide the functionality for manipulating an event driven datalayer. Here is the [documentation](https://github.com/adobe/adobe-client-data-layer/wiki)

Ideas for Supporting
- Add documentation of how to integrate with the Adobe Client Datalayer.
- Add documentation of how to send Alloy events based on events in the data layer.

Start by reviewing the Adobe Client Datalayer repository and its linked wiki, then compare the existing Alloy documentation to identify the appropriate location for integration guidance. Done means documenting how to integrate the datalayer with Alloy and how datalayer events should trigger Alloy events.
