Lets add test vectors for the per-record/per-file encode/decode of our various classes for the Elementary Files. We keep the test vectors as class variables of the respective EF-classes to ensure implementation and test vectors are next to each other. The test classes then iterate over all EF subclasses and execute the decode/encode functions using the test vectors from the class variables.
