瞄了一下OpenUI5中UI主题加载，关键点在sap.ui.core.Core.includeLibraryTheme方法。其调用者主要为：
- sap.ui.core.Core._boot：启动OpenUI5核心时加载必要的主题
- sap.ui.core.Core.initLibrary：加载某个库时会尝试加载其主题 假定config.js内容如下：
window['sap-ui-config'] = {
bindingSyntax: 'complex',
modules: [
"sap.m.library",
"sap.ui.commons.library",
"sap.ui.table.library",
"sap.ui.layout.library",
"yqu.ui.kexiao.library"
]
}
};
OpenUI5在加载yqu.ui.kexiao.library库时会尝试加载其主题。
