c2z 0.2.0

Feature

• Added the function Cristinunits to create a tibble with information about
  (nested) units in Cristin (e.g., A University -> Faculties -> Departments ->
  Groups). The tibble can than be used to extract data for each unit from Cristin.

• Added the function CristinMonthly to create a per month Zotero collections
  for units defined in Cristinunits. It may use the internal functions
  CristinMail and CristinWeb to create a newsletter using HTML for email and
  web, respectively.

Critical

• Fixed a bug in ZoteroFormat where parentCollection key, in some special
  cases, were identified as logical rather than character (Zotero uses a
  combination of logical and character in this field). The error caused an error
  in combining some collections.

• Fixed a bug in ZoteroWrangler where book sections with empty creators in
  main book caused a NA error.

Major

• Made a major revision of ZoteroLibray, making it less recursive and bloated.

Moderate

• Made handling of API status codes consistent throughout the package. Removed
  the now somewhat redundant debug checks.

Minor

• Fixed a bug in CristinWrangler where successfully identified duplicates with
  modified content in Cristin failed to update key, version and collections, thus
  creating new copies rather than updating existing items.

• Removed hyphens from ISBN when importing from Cristin to simplify filtering.

• Fixed a bug in CristinWrangler where remove.na was set to TRUE rather
  than forcing item-type to book (part_of) for book chapters.

• Fixed an issue in ZoteroLibrary where zero collections were reported when
  finding a specific collection key.

• Fixed an issue in ZoteroFormat where tags could be listed as either a
  data.frame or list

• Fixed an issue in CristinWrangler where creatorType of parent items are
  listed as authors when they are (most probably) editors.

• Fixed an issue in DoiCrossref where first and last names sometimes are
  switched due to an alt-name field in the XML.

• Fixed some issues with badges in README.

• Made some adjustments to ZoteroGet. bibliography now contains, in
  addition to bib, bib.body and bib.item separating style form the
  reference.

• Created an internal function called ZoteroId to extract ids from extra
  field.

• Added some internal functions to handle dates: Months to display
  (abbreviated) month names in Norwegian and English, ChangeDate to add/subtract
  date from date (e.g., days, weeks, months), FloorDate to set the first day of
  the month, and CeilingDate so set the last day of the month.

• Added a flowchart, why not.
