+Functional requirements - 16 points
+===================================
+* 1/1 The window should have a Play Scale button.
+* 1/1 The window should have a Stop Playing button.
+* 3/3 When the user clicks the Play scale button, a dialog appears asking the user for a note number in the range 0 to 115 (see the window on the right above). 
+* 1/1 Then an 8-note scale is played starting at the given note.
+* 1/1 The scale should be the usual Do Re Mi Fa Sol La Ti Do notes going up in pitch. 
+* 1/1 After playing the scale going up, it should then play the same scale again but going down from the highest note. 
+* 1/1 The user might click the Play scale button when a scale is already being played. If the user clicks OK, then the scale being played should immediately stop and the new scale should be played instead. If the user clicks Cancel, then the scale currently playing should continue playing.
+* 1/1 When the user clicks the Stop playing button, the scale should stop playing immediately. 
+* 1/1 The Play button and the Stop button should be visually distinct.
