Super simple apps, hostname config!

These apps are so simple that you may make one of them the YDK "hello world" example going forward    Here's how  to manage the host name on an IOS XR device: 

CRUD custom apps:

nc-create-xr-shellutil-cfg-20-ydk.py - set hostname

nc-delete-xr-shellutil-cfg-20-ydk.py - delete hostname (set default)

nc-read-xr-shellutil-cfg-20-ydk.py   - read/print hostname

nc-update-xr-shellutil-cfg-20-ydk.py - update hostname 

CRUD boilerplate apps:

nc-create-xr-shellutil-cfg-10-ydk.py - create boilerplate

nc-read-xr-shellutil-cfg-10-ydk.py   - read boilerplate

nc-update-xr-shellutil-cfg-10-ydk.py - update boilerplate

nc-delete-xr-shellutil-cfg-10-ydk.py - delete boilerplate 

Codec custom app:

cd-encode-xr-shellutil-cfg-20-ydk.py - hostname config 

Codec boilerplate app:

cd-encode-xr-shellutil-cfg-10-ydk.py - encode boilerplate 

With these apps, we just about reach 350 apps in the ydk-py-samples repository.  Enjoy!
