* Improve comparison and printing of Version There are two members in `Version`:` first` and `second`. There are many places where we need to print one `Version` object and compare two `Version` objects, but in the current code, these two members are accessed directly, which makes the code very tedious. This patch mainly do: 1. Adds overloaded methods for `operator<<()` for `Version`, so we can directly print a Version object; 2. Adds the `cantains()` method to determine whether it is an containment relationship; 3. Uses `operator==()` to determine if two `Version` objects are equal. Because there are too many places need to be modified, there are still some naked codes left, which will be modified later. This patch also removes some necessary header file references. No functional changes in this patch.
