+   Camera Module allows you to click images and take videos from smartphone by sending commands from your hardware.
+   This function demonstrates functions available in library for camera module. 
+
+   Open Serial monitor and follow the instructions printed there to take images and videos in different cases.
+
+   You can reduce the size of library compiled by enabling only those modules that you want
+   to use. For this first define CUSTOM_SETTINGS followed by defining INCLUDE_modulename.
