Created Functioning Vertical Sliders Per Route

[pinardo88]

1. Created a vertical slider for control of each route
2. Fixed the logic in past 'MainSlider' file so the slider index matches to the snapshot index. Vice versa,

• If you drag the slider down, the corresponding snapshots will match its index, and states will change accordingly on screen
• If you click on a specific snapshot, the slider will follow to the appropriate/ corresponding slider index
