This can cause headaches in the future, when users can't figure out why their step argument 'datatable' or 'docstring' does not get the value they expect
Fix casing of attributes of some parser classes (camel -> snake case)
Fix mistake that datatables are parsed the same as example tables.
Make data_table fixture only generated if a data table exists for a given step, otherwise the fixture is not generated.
Added methods to translate data table to a map/dict (using the first row as keys) and the ability to transpose the datatable for the case of vertical vs. horizontal data tables.
