##Setup
You will usually need to add at least two dependencies to use the API. Each tree implementation is in a separate module,
you will need to add the module for each tree implementation you wish to use. You will also need to add
trees-provider as a dependency, this dependency provides an implementation for the Trees class, builders and other
parts of the API that are not specific to a single tree.
Here is an example of how to add the API and immutable tree implementation to your project:
<dependency>
<groupId>com.mattunderscore.tree.root</groupId>
<artifactId>trees-provider</artifactId>
<version>0.10.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.mattunderscore.tree.root</groupId>
<artifactId>trees-immutable</artifactId>
<version>0.10.0-SNAPSHOT</version>
</dependency>
