  Your program should support shapes with anywhere from 7 up to (and including) 10 sides. 
  
  If a number of sides outside of this range is entered then your program should display an appropriate error message.
  
  1. If the input is 9 then display as Nanogon
  
  2. If the input is 10 display as Decagon
  
  3. If the input is any another number then display the message "Input should be from 7 to 10"
