   2c. the 12 files extracted were then merged into one signle .csv file
   2d. the columns of the file were modified to make them more readable
   2d. the merged file was then saved onto the local machine in preparation to be used in Tableau for analytics.

   (There a number of records that resulted in the age of bike rider to be 130 yrs in some cases)
5. Next a few worksheets were created that would help with showing the CitiBike Jersey Map and plot the Bike Stations with the bike usage data
