Moved REAMDE updates from #62 to a new PR since they were unrelated to the other changes there.

The conversation in #62 makes me wonder if we can work on a concise representation of the level of support that would supplement the verbose paragraphs for each scenario. My understanding is that there are two points leading to confusion:

• the level of support for target vs column type (see Support Dataset IDs and Image IDs when target is Project #65, populate command fails if the target is a plate and the CSV contains a plate column #51, populate metadata: Allow no Parent column #25, Support ROI table on Dataset, for table with ROI ID column #62, Support images_by_name for Screen and Plate #64). Is it possible to construct a table showing the different combinations?
• the command behavior if a n object cannot be resolved. My understanding is that the outcomes are: 1- error, 2- add an entry with -1, 3- ignore.

@will-moore my understanding is that the example from https://github.com/ome/omero-metadata/pull/71/files#diff-7b3ed02bc73dc06b7db906cf97aa91dec2b2eb21f2d92bc5caa761df5bbc168fR162 should cover this workflow. Should this be closed?
