v4.0.0

BREAKING CHANGE

• PR #162 Update java http client dependency to 4.1.0 from 2.3.4
• BIG thanks to Diego Camargo for the pull request!
• The breaking change is that variables that were public are now private and accessable only via getters and setters
• The Request object attributes are now only accessable through getters/setters
• request.method is now request.setMethod(string)
• request.endpoint is now request.setEndpoint(string)
• request.body is now request.setBody(string)
• The Response object attributes are now only accessable through getters/setters
• response.statusCode is now response.getStatusCode()
• response.body is now response.getBody()
• response.headers is now response.getHeaders()
• Adding a query parameter goes from:

Map<String,String> queryParams = new HashMap<String, String>();
request.addQueryParam("limit", "1");
queryParams.put("limit", "1");
request.queryParams = queryParams;

to:

request.addQueryParam("limit", "1");
