Run the report framework on multiple sets of results.

I would like to be able to run different tests on different architectures, and then merge the results into a single report.

Examples could be comparing different architectures (e.g. OSX or linux) or comparing different encoders that may only be available on certain architectures (e.g. Nvidia's h264 hardware encoder, vs. OSX Hardware encoder).

Issue 中没有指定文件、测试或入口点。首先定位报告框架，并了解它目前如何接收和合并一个结果集；完成的标准是能够比较不同架构或编码器的独立测试运行，并将其输出为一份报告。

由索引模型根据 Issue 内容生成。
