Fixed spinner issue. Related to using an integer array instead of a string array to create the resource.

Further attempts to fix spinner. Narrowed error down to null pointer at setAdapter line either spinner or adapter is null but on debug inspection this doesn't appear to be the case.

Added notification clicked class which will be the activity when a notification is clicked on. This will also add information to a file stored in external storage containing information about the notification. This will be compiled into statistics following a user trial.

Mid work commit with some sensors possibly implemented and notifications completed. Both are as yet untested.

Initial commit - some designs from pre-Christmas in addition to newly created java files. See logbook 9/1/18
