    /*This class manages a hair salon.  Global variables are used to keep
     track of dailyRevues (total $ coming in), dailyTax (total tax amount)
     and the number of hair cuts, permanents and colorings

     Also, the number of customers who have been serviced is to be kept track of

     A daily report is to be printed which gives the total number of customers,
     the total number of hair cuts, permanents and colorings.
     Also, the total amount of revenue (money taken in) and tax needs to be
     printed in the daily report.

     Finally, the average amount of money spent by each customer should be
     calculated and printed in the report.

     If the store brings in $650 or more, then the store manager receives 5% of
     the daily total revenue as a bonus.

   You should include the store manager bonus in your report and subtract it from
     the total revnue to give the net revenue for the day.

    Feel free to add additional variables and methods as you deem necessary
     See example report*/
