rorcid v0.7.0

MINOR IMPROVEMENTS

• orcid_search() changes: now returns number of records found as an attribute; get it by doing attr(x, "found") if x is the result of a call to orcid_search(). In addition, added an example of retreiving number of records found, as well as added more documentation to the function page on pagination. (#86)
• Auth gains a 3rd method: 2 legged OAuth. Updated ?orcid_auth docs on the 3 different auth methods, as well as the README and auth vignette. (#87)
