Prepare a mindmap example

[onierstrasz]

Ideas:

• mindmap of software language categories, with examples

Working on the HospitalSystem mindmap:

HospitalSystem new mindmap

TODO:

• map mindmap topics to node names (or descriptions?) -- current just says "Topic"

• add an announcement to update the graph when the style changes

• fix connections between nodes and edges

• links currently connect to circle around center instead of the bounded rectangle border

• set the link style (use sigmoid, or allow it to be changed)

• remove borders from Buttons in HypernodeEditor>>#contextMenu

• allow nodes to have custom color (background), font, weight etc

• add some behavior: check if mindmap is a tree; relayout from root; add menu to create a subnode
