- `home` is the name of the package you are building the plugin for, in most cases this is github.com/vulcanize/vulcanizedb
- `clone` this signifies whether or not to retrieve transformer packages by cloning them; by default we attempt to work with transformer packages located in
our `$GOPATH` but setting this to `true` overrides that. This needs to be set to `true` for the configs used in tests in order for them to work with Travis.
- `name` is the name used for the plugin files (.so and .go)
- `save` indicates whether or not the user wants to save the .go file instead of removing it after .so compilation (useful for debugging)
- `transformerNames` is the list of the names of the transformers we are composing together, so we know how to access their submaps in the exporter map
- `exporter.<transformerName>`s are the sub-mappings containing config info for the transformers
- `save` indicates whether or not the user wants to save the .go file instead of removing it after .so compilation. Sometimes useful for debugging/trouble-shooting purposes.
- `transformerNames` is the list of the names of the transformers we are composing together, so we know how to access their submaps in the exporter map
- `exporter.<transformerName>`s are the sub-mappings containing config info for the transformers
- `repository` is the path for the repository which contains the transformer and its `TransformerInitializer`
- `path` is the relative path from `repository` to the transformer's `TransformerInitializer`
- `type` is the type of the transformer; indicating which type of watcher it works with (for now, there are only two options: "eth_event" and "eth_storage")
- "eth_storage" indicates the transformer works with the [storage watcher](https://github.com/vulcanize/maker-vulcanizedb/blob/compose_and_execute/libraries/shared/watcher/storage_watcher.go)
that fetches state and storage diffs from an ETH node (instead of, for example, from IPFS)
- "eth_event" indicates the transformer works with the [event watcher](https://github.com/vulcanize/maker-vulcanizedb/blob/compose_and_execute/libraries/shared/watcher/event_watcher.go)
that fetches event logs from an ETH node
- `migrations` is the relative path from `repository` to the db migrations for the transformer
- `path` is the relative path from `repository` to the transformer's `TransformerInitializer` directory (initializer package)
- `type` is the type of the transformer; indicating which type of watcher it works with (for now, there are only two options: `eth_event` and `eth_storage`)

To plug in an external transformer we need to:

that exports a variable `TransformerInitializer` or `StorageTransformerInitializer` that are of type [TransformerInitializer](https://github.com/vulcanize/maker-vulcanizedb/blob/compose_and_execute/libraries/shared/transformer/event_transformer.go#L33)
