high- vs. low-level interfaces

Each function has a higher level interface that does HTTP request for data and parses the JSON using jsonlite. This is meant for those who want everything done for them, but there's a time penalty for as the parsing adds extra time. If you just want raw JSON unparsed text, you can use the low level interface.

The low level version of each function has _ at the end (e.g., core_search_), while the high level version doesn't have the _ (e.g., core_search).

The high level version of each function uses the low level method, and the low level method does all the logic and HTTP requesting, whereas the high level simply parses the output.
