* Writes the receivers plist representation into an
* .eomodeld file wrapper located at path.
* Depending on the the path extension .eomodeld or .eomodel
* the corresponding format will be used.
* If the path has neither .eomodeld nor .eomodel path
* extension, .eomodeld will be used.
* If the file located at path already exists, a back is created
* by appending a '~' character to file name.
* If a backup file already exists, when trying to create a backup,
* the old backup will be deleted.
* If any of the file operations fail, an NSInvalidArgumentException
* will be raised.
