Needs better documentation

[knopkem]

Hi,
first of all, good work so far. I could easily get started with latest unity and create a simple tree.
I could also create a custom task using your example from the readme. One problem I have is how a task can be written for a specific game object. Since tasks are scriptable objects this doesn't seem to be so simple. (I could probably find the object and perform some action (e.g. using the navigation agent to move to a new target), however this would be very slow.
I'm sure that I must be doing something wrong but I feel that either adding some more advanced examples or writing a documentation would help. (I know it's still in progress and these things might be already planned, but I'm just impatient).
regards
