Basic Behaviour Tree with code

Basic A* Implemented (requires further fixes) c381a1e1c7b4c2567e576bc6d7bdbf9799e0a6fc

A* works, however the obstacles are only being set to center position.

@Ryan-Fletcher Can we have an update please?

[Ryan-Fletcher]

Using Behaviour Bricks, implemented an AI that can switch between Wandering the area and searching for resources.

AI successfully searches for resources, however there's an issue switching from resource back to wander script.

[Ryan-Fletcher]

Committed the behaviour tree to the BehaviourTree branch.

Implemented spawners for the animals, and the humans can successfully chase them down (need to add damage and harvesting behaviour).

[Ryan-Fletcher]

Harvest script has been made, needs more changes before committing

[Ryan-Fletcher]

Health and Damage scripts have been implemented, however the health doesn't increment correctly and sometimes causes the human's target's game object to be set to null.

[Ryan-Fletcher]

Created a new damage script that's ranged instead of melee. This should be easier to recognise damage dealt and should stop objects from rubbing into each other. Will push into repository tomorrow as the labs are closing.

[Ryan-Fletcher]

Committed my current work. Haven't been able to get the updated scenes as for some reason it takes hours just to open the master version in Unity and often freezes. Will try at home if this is an issue in the labs.
