Swagger header params incorrectly appended to path

[donaldoakes]

Live Swagger documentation generated from @Api annotations erroneously include header params on the path. For example, the following annotation appends {hdrparam} to the path in swagger.json and swagger.yaml:

    @ApiImplicitParams({
        @ApiImplicitParam(name="hdrparam", paramType="header", required=true, dataType="java.lang.String")
    })
    public JSONObject get(String path, Map<String,String> headers) throws JSONException {
        // ...
    }
