				// hierarchical.levelSeparation	Number	150	The distance between the different levels.
				// hierarchical.nodeSpacing	Number	100	Minimum distance between nodes on the free axis. This is only for the initial layout. If you enable physics, the node distance there will be the effective node distance.
				// hierarchical.treeSpacing	Number	200	Distance between different trees (independent networks). This is only for the initial layout. If you enable physics, the repulsion model will denote the distance between the trees.
				// hierarchical.blockShifting	Boolean	true	Method for reducing whitespace. Can be used alone or together with edge minimization. Each node will check for whitespace and will shift it's branch along with it for as far as it can, respecting the nodeSpacing on any level. This is mainly for the initial layout. If you enable physics, they layout will be determined by the physics. This will greatly speed up the stabilization time though!
				// hierarchical.edgeMinimization	Boolean	true	Method for reducing whitespace. Can be used alone or together with block shifting. Enabling block shifting will usually speed up the layout process. Each node will try to move along its free axis to reduce the total length of it's edges. This is mainly for the initial layout. If you enable physics, they layout will be determined by the physics. This will greatly speed up the stabilization time though!
				// hierarchical.parentCentralization	Boolean	true	When true, the parents nodes will be centered again after the the layout algorithm has been finished.
				// hierarchical.direction	String	'UD'	The direction of the hierarchical layout. The available options are: UD, DU, LR, RL. To simplify: up-down, down-up, left-right, right-left.
				// hierarchical.sortMethod	String	'hubsize'	The algorithm used to ascertain the levels of the nodes based on the data. The possible options are: hubsize, directed.
        //
				// Hubsize takes the nodes with the most edges and puts them at the top. From that the rest of the hierarchy is evaluated.
        //
				// Directed adheres to the to and from data of the edges. A --> B so B is a level lower than A.
