Get metadata from SoilProfileCollection. Result is a list. Two entries (aqp_df_class, depth_units) should not be edited in the metadata list directly. There are methods that facilitate changing them -- and propagating their changes throughout the collection. Otherwise, metadata list is a free-form slot used to store arbitrary information about the data, how it was collected, citations, etc.
