/**
* Hapi伺服器端之資料控制與同步器
*
* @class
* @param {Object} [opt={}] 輸入設定物件，預設{}
* @param {Integer} [opt.port=8080] 輸入Hapi伺服器通訊port，預設8080
* @param {Boolean} [opt.useCors=true] 輸入是否API可跨域呼叫，預設true
* @param {Boolean} [opt.useInert=true] 輸入是否使用@hapi/inert取得指定資料夾下所有靜態檔案，預設true
* @param {String} [opt.pathStaticFiles='dist'] 輸入當useInert=true時指定伺服器資料夾名稱，預設'dist'
* @param {Array} [opt.apis=[]] 輸入Hapi伺服器設定API陣列，預設[]
* @param {Function} [opt.getUserIDFromToken=async ()=>''] 輸入取得使用者ID的回調函數，傳入參數為各函數的原始參數，預設async ()=>''
* @param {Boolean} [opt.useDbORM=true] 輸入是否使用資料庫ORM技術，給予false代表不使用直接存取資料庫函數與自動同步資料庫至前端功能，預設true
* @param {Object} [opt.dbORMs={}] 輸入各資料表的操作物件，用以提供由tableNamesSync指定資料表的change事件，使能監聽與觸發資料變更事件，key為表名而值為該表的操作器實體，操作器實體可使用例如WOrmMongodb等建立，預設{}
* @param {Function} [opt.operORM={}] 輸入各資料表的操作通用接口物件，用以提供操作由tableNamesExec指定資料表的例如'select'、'insert'、'save'、'del'函數。加上由extFuncs提供的函數，就為全部可由前端執行的函數，預設{}
* @param {Array} [opt.tableNamesExec=[]] 輸入指定能被操作的表名陣列，預設[]
* @param {Array} [opt.methodsExec=['select','insert','save','del']] 輸入指定綁定操作器的方式陣列，可選'select'、'insert'、'save'、'del'、'delAll'，預設['select', 'insert', 'save', 'del']
* @param {Array} [opt.tableNamesSync=[]] 輸入指定能被同步的表名陣列，預設[]
* @param {Object} [opt.extFuncs=null] 輸入額外擴充執行函數物件，key為函數名而值為函數，預設null
* @param {Function} [opt.hookBefores=null] 輸入執行函數的前攔截函數，預設null
* @param {Function} [opt.hookAfters=null] 輸入執行函數的後攔截函數，預設null
* @param {Boolean} [opt.showLog=true] 輸入是否使用console.log顯示基本資訊布林值，預設true
* @returns {Object} 回傳物件，其內server為hapi伺服器實體，wsrv為w-converhp的伺服器事件物件，wsds為w-serv-webdata的伺服器事件物件，可監聽error事件
