Added the permission to write to the External SD within the Android manifest. This implicitly allows reads.
Created the start of the profile picture taking facility within the teacher creator. It can currently load up and use the camera to grab a photo. But currently nothing is done with this photo. The aim will be to place it in the area where the current ImageView is.
Aim will be to withdraw some of this method out into another java class to it can be reused within the student profile creation section.
