Resolve merge conflicts: Force overwrite all files

There are three simple solutions to copy the last version that is in you remote repository, discarding all changes that you have made locally:

1. Discard your repository and clone again. This is the most simple solution, but if your repository is big, it can take a long time, and may require extra effort like reconfigureing, etc.

2. Discard the local changes with git reset --hard <hash> and then do a git pull. The problem is you need to first find a commit that precedes whatever change history you are trying to avoid. After resetting to that commit hash, do a git pull.

3. Do a git fetch to bring the updates to your local reference of the remote branch (usually origin/master) and then do a git reset --hard passing this reference, ie, git reset --hard origin/master.
