    Adds the FEATURES parameter and then delegates to addParameters(Map).

    getParameterInfo in class SingleProcessFactory
  - addParameters
```
protected abstract void addParameters(Map<String,Parameter<?>> parameters)
```
    Method for subclasses to add parameter descriptors for the process.
    Subclasses should not add a parameter for the input feature collection as this is done by the case class. Example implementation for a simple buffer example:
    protected void addParameters(Map<String, Parameter<?>> parameters) { parameters.put(BUFFER.key, BUFFER); }
