Does this test ensure that 'field2' has been removed?
> Create a fieldMapping functionality which allows for parsed fields to be

> Currently the parsers take care of transforming raw data to the parsed JSON
> representation. Allow for a layer to be placed at a sensor level to
> transform input fields from the parsed messages to create new fields. For
> instance, mapping IANA protocol numbers to a standardized textual
> representation (i.e. 6 maps to TCP).
