redcapAPI: Go Royals

Changes in Version 1.0.1 (2014-10-20)

• Bug fix: in importRecords meta data was not previously exported when a project info object was not provided. This is now corrected
• Bug fix: in exportRecords and exportReports, the checkbox labels weren't being returned as factor levels when checkboxLabels=TRUE. The behavior is now consistent with expectations.
• Bug fix: in compareRedcapVersion, a logical check was failing due to an ommitted argument in grepl. This has been corrected.
• added function apiCall. This wraps a call to tryCatch. If a Gnu/TLS recv error is returned, the encoding is changed from 'gzip' to 'identity' to successfully retrieve the API response.
• tryCatch calls are added to redcapProjectInfo to prevent fatal errors when one of the API functions casts an error. The output is modified to indicate where the problem occurred. This is most likely to affect exportUsers. An unresolved issue behind this is logged in the issues on Github.
