Initial commit by xsrc
since xFaceLib contains doc, demo and script, create lib plugin for that , xmen will add it to engine
Merge branch 'dev' of gitlab.polyvi.com:xface/xface-extra-lib into dev
Add xfaceLib doc and demo
基本实现ios平台库模式打包

主要思路是通过脚本修改开发工程的target，并去掉一些不需要的资源，
然后使用xcodebuild生成.a文件，并与其它资源打包成最终的sdk
解决ios平台编译库时路径拼接不对的问题
1. package demo and doc to xFaceLib.zip when building with lib mode 2. update lib and res and app of demo to lateset when building with lib mode
Merge branch 'dev' of gitlab.polyvi.com:xface/xface-extra-lib into dev
1. using asset tag instead of source-file tag to copy dir 2. rename xFaceLib to xfaceSdk to keep the same with ios
支持ios平台生成模拟器版本的sdk包
ios平台库模式打包时拷贝其它需要的cordova头文件，将需要的framework写到readme中
将cordova的头文件拷贝到cordova目录下
ios平台库模式下将所有的public头文件拷贝到导出的压缩包中
