- Remove some unnecessary code: IsHeaderFile is no longer required, as the logic to find flags to headers is now built into YCM - Add function to make paths in flags absolute: It seems YCM is not correctly resolving paths in flags to consider `build` as the compiler working directory. - Update documentation.
