Noticed that ClientErrorResponseException and ServerErrorResponse had been changed to ClientException and ServerException, respectively, but hadn't been changed in the docs.
- Adding the json request option to provide better symmetry
between request and response APIs.
- Updating the quickstart guide and documentation.
- Closes#674
- Adding more docs on error handling
- Tightening down the client interface to only allow RequestExceptions to be
thrown from a client during a send() method. This makes error handling much
easier and predictable.
- HTTP method based signatures like get(), put(), etc.. accept a URL,
and array of request options. createRequest() is similar but also requires
a method string.
- Renamed request events to 'before', 'complete', 'error', and 'headers.
- Renamed the associated event classes.
- Adding more docs.
- Instead of using a HeaderValues object for header values, I've added an
optional argument to getHeader() that specifies whether or not to return
a header as a string or an array.
- Adding the start of the new documentation.
