The API Application

An API Application is an API implementation which builds it's contents by including a number of builders, an them activating them with various implementations.

The reasoning for the application approach is:

1. any api consumer will want to hardcode it's go library includes for the coach providers, an likely build it's builders before activating them
2. most api consumers will want some dynamic run-time configuration of the builders which cannot be hardcoded into the go code, and which will come from some central configuration.

So the typical app building approach is:

1. Create an instance of the application struct that you like
2. Create any builders from implementations that you like, including their go library, and configuring their structs
3. Add each builder that should be avaialable to the application using the AddBuilder() method
4. Decide what implementations you would like to activate (perhaps from some configuration source) and for each implemtnatipo
5. Activate builders in a sequence that makes sense for you app. Sometimes one builder may require operations from a different builder, so this sequence is important.
