Fixed the rauxstore such that you can properly read from it (also updated the tests)
- The RAuxStore now keeps track of which entry to read
- auxFieldType now takes fieldname as a parameter rather than trying to access it within the function
- the getEntry method now has a correct object associated with the field
- The RAuxStore can now access the data using the getData method. Tests have been made to ensure this.
