Include indirect dependencies

[astrowalker]

This project looks interesting but from what I see after test run it includes only direct dependencies. I.e. let's say I have project P which has nuget N installed, but this package requires package R, I will see in the output only P->N dependency, R is off the radar.

It would be great if user would have an option, either use only direct dependencies (like today) or get full list of dependencies:

### P
  - N
     * R

so each level would be intended.
