/**
 * BEM 类名生成器
 * @param block 块名
 * @returns 返回 BEM 命名空间的函数
 *
 * @example
 * const bem = createBEM('ea-alert');
 *
 * // 基础类名
 * bem()                          // 'ea-alert'
 * bem.b()                        // 'ea-alert'
 * bem.cb()                       // '.ea-alert'
 *
 * // 元素类名 (block__element)
 * bem.e('content')               // 'ea-alert__content'
 * bem.ce('content')              // '.ea-alert__content'
 *
 * // 修饰符类名 (block--modifier)
 * bem({ primary: true })         // 'ea-alert ea-alert--primary'
 * bem({ effect: 'light' })       // 'ea-alert ea-alert--effect-light'
 * bem.m('primary', 'large')      // 'ea-alert--primary ea-alert--large'
 * bem.cm('primary')              // '.ea-alert--primary'
 *
 * // 状态类名 (is-state)
 * bem({}, { center: true })      // 'ea-alert is-center'
 * bem.s('active', 'disabled')    // 'is-active is-disabled'
 * bem.cs('active')               // '.is-active'
 *
 * // 组合使用
 * bem({ primary: true }, { center: true })  // 'ea-alert ea-alert--primary is-center'
