+Original Script By: Ditzel
+Youtube Video Link: https://www.youtube.com/watch?v=KkYco_7-ULA&ab_channel=DitzelGames
+Uses of this script:
+ For controlling camera movement: Pan, zoom and rotate
+How to use:
+Set this on an empty game object positioned at (0,0,0) and attach your active camera.
+The script only runs on mobile devices or the remote app.
+DecreaseCameraPanSpeed - The more the value, the greater it slows the pan speed
+Upper height (Zoom out restriction) - Relative to camera position (not worldspace)
+Lower height (Zoom in restriction) - Relative to camera position (not worldspace)
+------[CHANGE LOG]------
+Edited by Kudoshi : 24/3/2021
+- Added Zoom In Out restriction
+- Added camera pan speed
