citecorp v0.3.0

NEW FEATURES

• oc_coci_refs(), oc_coci_cites(), and oc_coci_citation() now support more than one DOI or COCI identifier passed in. oc_coci_meta() already supported more than one identifier; now all four oc_coci* methods support more than one identifier. The caveat is that the API route behindn oc_coci_meta() supports >1 identifier in a single http request - whereas the API routes behind the other functions only support one identifier per request, so they make an http request for each identifier passed in (#6)

MINOR IMPROVEMENTS

• added tests for Cloudflare http status codes (#7)
