Wrapped examples requiring token in \donttest instead of \dontrun
Fixed minor spacing issue in description
Resubmission
I have fixed the following issues as per comments for the last submission.
Fixed authors field - changed 'Author' field to 'Authors@R'
Fixed description - corrected spelling errors, added web links, elaborated on package functionality
Removed examples for unexported functions
Regarding the removal of 'donttest' around examples: All functions require an API key hence there is currently no way of providing examples without wrapping them in donttest. Although some examples will print errors, functions currently have error handling and should return an output; hence they are wrapped in 'donttest' instead of 'dontrun'.
