Moves prep.tree into the main SRCGrob function. This simplifies the process of creating a tree. Before, the user needed to call prep.tree separately, then pass the correct output values into SRCGrob. This was unintuitive and error-prone.
This change also allows prep.tree to be private. Some unnecessary inputs to prep.tree were removed, and SRCGrob inputs have been changed to pass data to prep.tree.
