converted a few functions for scale mode - not finished
scale mode and chord mode work for basic clicking
clearClickedNotes working like clearPlacedNotes
ran code through beautifier
moved some functions around
updated test page for placed notes click
concept of placed notes has been removed as it gets too confusing - user will set colors
fixed bug where you click a different note on a string, add a string and the result is a hovered note. Also some cleanup
removed some logic outside of the draw method
adding/removing appears to work in both scale and chord mode
ran through beautifier

colors can be set on clicked notes and they are maintained when strings are added
