+* Added `pod init` command which generates a Podfile according to the
+  targets of the project stored in the working directory and to the templates
+  stored in the `~/.cocoapods/templates` folder. Tow templates are supported: 
+    - the `Podfile.default` template for regular targets.
+    - and the `Podfile.test` template for test targets.
