Working on adding in file reading. The file is made in the /images folder. Will set it up so that this file goes in on the launch file to the parameters server, and when initializing the image switcher class it will read that off of there.
Adding image_files.txt the textfiles which has the filenames and modes for the image switcher.
Adding rosparam line to startup.launch. The other way to do this would be to put the dictionary either in a yaml file or in the launch file directly and then load the dictionary directly from the server instead of loading the filename. I thought this way would be more modular.
