Initial commit
Added documentation to README file.
Removed ::::bash markdown tag (bad github interpretation)
Added --dont_remove_project option.

When this option is enabled, the script deletes every project
resources, but exits without deleting the project itself.
Remove 'default' security group from list

Default security group cannot be removed. Therefore, removing it from
the list of resources to be deleted.
Improved --dry_run display

Added space between types of resources
Updated README example

The example now provides the steps to:
* Check what resources are still in a project
* Remove these resources without deleting the project
* Check that the project is empty
* Remove the project
Added installation instructions

endpoints are not found.
