/**
* 建立http API使用者(Node.js與Browser)端物件
*
* @param {Object} opt 輸入設定參數物件
* @param {String} [opt.url='http://localhost:8080/api'] 輸入http API伺服器網址，預設為'http://localhost:8080/api'
* @param {String} [opt.token='*'] 輸入使用者認證用token，預設為'*'
* @param {Function} opt.error 輸入監聽error函數
* @param {Function} opt.reconn 輸入監聽reconn函數
* @returns {Promise} 回傳Promise，resolve為映射伺服器端可用函數之物件，各函數輸入皆為單一物件，各函數回傳皆為Promise，用resolve與reject處理回傳結果
* @example
*
* import WComorHapiClient from 'w-comor-hapi/dist/ws-client-node.umd.js'
*
* //opt
* let opt = {
* url: 'http://localhost:8080/api',
* token: '*',
* error: function(err) {
* console.log('client: error:', err)
* },
* reconn: function() {
* console.log('client: reconn')
* },
* }
*
* //WComorHapiClient
* new WComorHapiClient(opt)
* .then(function(wo) {
* console.log('client: funcs: ', wo)
*
* function core(ps) {
* wo.group.plus(ps)
* .then(function(r) {
* console.log('client: plus(' + JSON.stringify(ps) + ')=' + r)
* })
* .catch(function(err) {
* console.log('client: plus: catch: ', err)
* })
* wo.group.div(ps)
* .then(function(r) {
* console.log('client: div(' + JSON.stringify(ps) + ')=' + r)
* })
* .catch(function(err) {

* console.log(`client: add(${JSON.stringify(ps)})=${r}`)
* })
* .catch(function(err) {
* console.log('client: add: catch: ', err)
* })
* wo.minu(ps)
* .then(function(r) {
* console.log(`client: minu(${JSON.stringify(ps)})=${r}`)
* })
* .catch(function(err) {
* console.log('client: minu: catch: ', err)
* })
