v0.6.4

This is a significant update, but not crucial. It enhances usability and remedies some nagging issues.

NEW

• check for "https" in sysmeta update functions
• helper for setting project data
• logic for multiple roles
• check to see if sysmeta fileName is already equal to user input
• Travis CI support
• eml_abstract helper
• if statement in set_public_read
• EML object as an alternative option for metadata_path in publish_update
• error checking logic for personnel passed to eml_project
• arguments for studyAreaDescription and designDescription
• example for resource map parsing

FIXED

• updated error catches to include messages
• updated eml@packageId element in update_object
• replaced length() with nchar() in set_abstract since we are evaluating if a String is >0 characters
• missing docs for update_object
• modified publish_update to only remove eml@access if metadata_path is not null
• updated eml_party to include case for personnel

• tests and built .Rds for projects
