/**
* @param element A base element for the eg.Flicking module. When specifying a value as a `string` type, you must specify a css selector string to select the element.eg.Flicking 모듈을 사용할 기준 요소. `string`타입으로 값 지정시 요소를 선택하기 위한 css 선택자 문자열을 지정해야 한다.
* @param options An option object of the eg.Flicking moduleeg.Flicking 모듈의 옵션 객체
* @param {string} [options.classPrefix="eg-flick"] A prefix of class name will be added for the panels, viewport and camera.패널들과 뷰포트, 카메라에 추가될 클래스 이름의 접두사.
* @param {number} [options.deceleration=0.0075] Deceleration value for panel movement animation for animation triggered by manual user input. Higher value means shorter running time.사용자의 동작으로 가속도가 적용된 패널 이동 애니메이션의 감속도. 값이 높을수록 애니메이션 실행 시간이 짧아진다.
* @param {boolean} [options.horizontal=true] Direction of panel movement. (true: horizontal, false: vertical)패널 이동 방향. (true: 가로방향, false: 세로방향)
* @param {boolean} [options.circular=false] Enables circular mode, which connects first/last panel for continuous scrolling순환 모드를 활성화한다. 순환 모드에서는 양 끝의 패널이 서로 연결되어 끊김없는 스크롤이 가능하다.
* @param {boolean} [options.infinite=false] Enables infinite mode, which can automatically trigger needPanel until reaching last panel's index reaches lastIndex무한 모드를 활성화한다. 무한 모드에서는 needPanel 이벤트를 자동으로 트리거한다. 해당 동작은 마지막 패널의 인덱스가 lastIndex와 일치할때까지 일어난다.
* @param {number} [options.infiniteThreshold=0] A Threshold from viewport edge before triggering `needPanel` event in infinite mode.무한 모드에서 `needPanel`이벤트가 발생하기 위한 뷰포트 끝으로부터의 최대 거리.
* @param {number} [options.lastIndex=Infinity] Maximum panel index that Flicking can set. Flicking won't trigger `needPanel` when event's panel index is greater than it.
Also, if last panel's index reached given index, you can't add more panels.Flicking이 설정 가능한 패널의 최대 인덱스. `needPanel` 이벤트에 지정된 인덱스가 최대 패널의 개수보다 같거나 커야 하는 경우에 이벤트를 트리거하지 않게 한다.
또한, 마지막 패널의 인덱스가 주어진 인덱스와 동일할 경우, 새로운 패널을 더 이상 추가할 수 없다.
* @param {number} [options.threshold=40] Movement threshold to change panel(unit: pixel). It should be dragged above the threshold to change current panel.패널 변경을 위한 이동 임계값 (단위: 픽셀). 주어진 값 이상으로 스크롤해야만 패널 변경이 가능하다.
* @param {number} [options.duration=100] Duration of the panel movement animation.(unit: ms)패널 이동 애니메이션 진행 시간.(단위: ms)
* @param {function} [options.panelEffect=x => 1 - Math.pow(1 - x, 3)] An easing function applied to the panel movement animation. Default value is `easeOutCubic`.패널 이동 애니메이션에 적용할 easing함수. 기본값은 `easeOutCubic`이다.
* @param {number} [options.defaultIndex=0] Index of panel to set as default when initializing. A zero-based integer.초기화시 지정할 디폴트 패널의 인덱스로, 0부터 시작하는 정수.
* @param {string[]} [options.inputType=["touch,"mouse"]] Types of input devices to enable.({@link https://naver.github.io/egjs-axes/release/latest/doc/global.html#PanInputOption Reference})활성화할 입력 장치 종류. ({@link https://naver.github.io/egjs-axes/release/latest/doc/global.html#PanInputOption 참고})
* @param {number} [options.thresholdAngle=45] The threshold angle value(0 ~ 90).
If input angle from click/touched position is above or below this value in horizontal and vertical mode each, scrolling won't happen.스크롤 동작을 막기 위한 임계각(0 ~ 90).
클릭/터치한 지점으로부터 계산된 사용자 입력의 각도가 horizontal/vertical 모드에서 각각 크거나 작으면, 스크롤 동작이 이루어지지 않는다.
* @param {number|string|number[]|string[]} [options.bounce=[10,10]] The size value of the bounce area. Only can be enabled when `circular=false`.
You can set different bounce value for prev/next direction by using array.
`number` for px value, and `string` for px, and % value relative to viewport size.(ex - 0, "10px", "20%")바운스 영역의 크기값. `circular=false`인 경우에만 사용할 수 있다.
배열을 통해 prev/next 방향에 대해 서로 다른 바운스 값을 지정 가능하다.
`number`를 통해 px값을, `stirng`을 통해 px 혹은 뷰포트 크기 대비 %값을 사용할 수 있다.(ex - 0, "10px", "20%")
* @param {boolean} [options.autoResize=false] Whether resize() method should be called automatically after window resize event.window의 `resize` 이벤트 이후 자동으로 resize()메소드를 호출할지의 여부.
* @param {boolean} [options.adaptive=false] Whether the height(horizontal)/width(vertical) of the viewport element reflects the height/width value of the panel after completing the movement.목적 패널로 이동한 후 그 패널의 높이(horizontal)/너비(vertical)값을 뷰포트 요소의 높이/너비값에 반영할지 여부.
* @param {number} [options.zIndex=2000] z-index value for viewport element.뷰포트 엘리먼트의 z-index 값.
* @param {boolean} [options.bound=false] Prevent view from going out of first/last panel. Only can be enabled when `circular=false`.뷰가 첫번째와 마지막 패널 밖으로 나가는 것을 막아준다. `circular=false`인 경우에만 사용할 수 있다.
* @param {boolean} [options.overflow=false] Disables CSS property `overflow: hidden` in viewport if `true`.`true`로 설정시 뷰포트에 `overflow: hidden` 속성을 해제한다.
* @param {string} [options.hanger="50%"] Reference position of hanger in viewport, which hangs panel anchors should be stopped at.
Should be provided in px or % value of viewport size.
You can combinate those values with plus/minus sign
ex) "50", "100px", "0%", "25% + 100px"뷰포트 내부의 행어의 위치. 패널의 앵커들이 뷰포트 내에서 멈추는 지점에 해당한다.
px값이나, 뷰포트의 크기 대비 %값을 사용할 수 있고, 이를 + 혹은 - 기호로 연계하여 사용할 수도 있다.
예) "50", "100px", "0%", "25% + 100px"
* @param {string} [options.anchor="50%"] Reference position of anchor in panels, which can be hanged by viewport hanger.
Should be provided in px or % value of panel size.
You can combinate those values with plus/minus sign
ex) "50", "100px", "0%", "25% + 100px"패널 내부의 앵커의 위치. 뷰포트의 행어와 연계하여 패널이 화면 내에서 멈추는 지점을 설정할 수 있다.
px값이나, 패널의 크기 대비 %값을 사용할 수 있고, 이를 + 혹은 - 기호로 연계하여 사용할 수도 있다.
예) "50", "100px", "0%", "25% + 100px"
* @param {number} [options.gap=0] Space between each panels. Should be given in number.(px).패널간에 부여할 간격의 크기를 나타내는 숫자.(px)
* @param {eg.Flicking.MoveTypeOption} [options.moveType="snap"] Movement style by user input.(ex: snap, freeScroll)사용자 입력에 의한 이동 방식.(ex: snap, freeScroll)
* @param {boolean} [options.collectStatistics=true] Whether to collect statistics on how you are using `Flicking`. These statistical data do not contain any personal information and are used only as a basis for the development of a user-friendly product.어떻게 `Flicking`을 사용하고 있는지에 대한 통계 수집 여부를 나타낸다. 이 통계자료는 개인정보를 포함하고 있지 않으며 오직 사용자 친화적인 제품으로 발전시키기 위한 근거자료로서 활용한다.
