Misc. improvements to vICN codebase detailed below.

- vICN core
 . Added python setup script (allowing package installation)
 . Better error handling
- Resources
 . LXD : better handling of certificate generation
 . Physical : generation of SSH keypair within vICN
 . Link : code simplification
 . EmulatedLteChannel: fixed typo in netmask configuration of emu-radio (missing /)
- Examples
 . Added json file for tutorial #2 - Dumbell
 . New tutorial #03 - Load balancing in WiFi/LTE hetnet
- Other minor changes incl. code cleanup (trailing spaces, etc.)
