Detailed Description

This class extends Element to represent general trees with arbitrary number of children.

TreeElement nodes can have an arbitrary number of child nodes(held in in a vector in the order in which they were added). The visualization of trees assumes that the children are drawn in order from left to right.

Tree Elements have labels (string) that are displayed on the visualization. Elements take an generic object E as a user defined parameter, which can be any native type or object.

Elements contain a visualizer (ElementVisualizer) object for setting visual attributes (color, shape, opacity, size), necessary for displaying them in a web browser.

Elements also have a LinkVisualizer object that is used when they are linked to another element, appropriate for setting link attributes, between parent and child nodes.
