susoapi 0.2.0

New features

• Credentials now include the workspace. set_credentials() now has a workspace argument. All functions that target workspaces now draw from these credentials (#24, #26, h/t @ashwinikalantri).
• Interview attributes can now be user-specified. Through the nodes argument of get_interviews(), users may specify as few or as many nodes of information about interviews as needed. If nothing is specified, the default is to fetch all nodes. If something is specified, it must include id and may include other things (#23).

Breaking changes

• Credentials used in all functions now expect workspace. Users will need to use set_credentials() to add this component to their .Renviron file.

Minor improvements and bug fixes

• Fixed help pages where documentation suggested that logical values be provided as strings rather than as the logical values that the code required (#25, h/t @ashwinikalantri).
• Fixed issue where failure to specify qnr_version in get_assignments() lead to the function returning all assignments for all questionnaires (#27, h/t @ashwinikalantri).
• Added checks for arguments throughout--typically logical values, user names, and dates for time intervals--and tests to ensure those checks work correctly.
• Convert NA_character_ comments to empty strings before forming the request in interview functions.
• Added a private function is_user_name() to check whether user-provided user names followed Survey Solutions rules about character length and content.
• Revised order of arguments and documentation for credentials: server, workspace, user, password.
