+ * Task for Force Updating a Working Copy
+ * 
+ * 'git fetch' downloads the latest from remote without trying to merge or rebase anything.
+ * 'git reset' resets the master branch to what you just fetched. 
+ * The '--hard' option changes all the files in your working tree to match the files in origin/master,
+ * so if you have any local changes, they will be lost.
