        //3.  Can you write a SOQL query from scratch that will return the top 10 Accounts in the org, ordered by annual
        //revenue in decending order?  Print your results in the debug log.


        //4.  Can you write a SOQL query that will return all opportunities for all accounts in the topFiveAccounts list that we used
        //in Number 1?  (topFiveAccounts) Hint:  If you're stuck, look back a the code in WeekFiveClassExercises, getOpenOppsForHotAccounts method
        //  Print your results in the debug log.

        // Can you replace the ?? with the number that makes sense based on the comments?
        // Remove the slashes and compile.
        // Can you add an extra counter variable so that you can print out how many times the loop ran in total?

        //each account name in the debug log when you're done.
        //Use the list size to tell you how many loops, and use indexing to fetch values.  If you need help, check the
        //loopingThroughLists method in WeekFiveClassExercises for hints
