Groupby / ixref tutorial enhancement
Is your feature request related to a problem? Please describe. The examples in the tutorial at https://pathway.com/developers/user-guide/data-transformation/indexing-grouped-tables don't mention the name / identifier of the employee in any column in the source data. This makes it harder to tell apart groupby results (aggregates) from source data.
Describe the solution you'd like Update the tutorial, e.g., add first names of employees as an extra column in input example tables (Alice, Bob, Charlie, etc.). Leaving decisions / priorities to @olruas.
Describe alternatives you've considered n/a.
Additional context This could also make the tutorial more immediately relatable when comparing to SQL-windowing syntax like in #19.
