readme recompiled (fix parsing error)
rdfa example added
validates but fails ref/id check, not sure why
started S4 class-based approach for cleaner more flexible interface
writing continues, various edits
updated documentation (autogenerated)
questions for Duncan (should probably move to issues tracker once we have Github connection again)
Default copyright clause added to eml_dataset
ideally this should instead become part of the prototype in the S4 model
rdf example, valid but probably less useful than the rdfa
examples of what S4 coercion methods might look like; still working out questions
hack date formats for the moment
Testing S4 based approach
Working on S4 methods
passing unit tests in S4.R
working on S4 version
unit tests for S4
updated documentation
draft methods output file
inst/tests/S4_write.R not passing
Progress! Working write_eml methods now, mostly working read_eml methods
The write_eml approach uses a custom function in place of coercions, and probably should be written as a method instead.
The read_eml approach modifies XML::xmlToS4 to handle ListOf option.  Both need tests written still
start cleaning out depricated (non S4) functions
