Todo

Things waiting to be implemented:

• abstract edit mode (so people can implement thir own edit forms)
• Sometimes, when hiding a nodes children (especially if it has only one child), the line between them doesn't disappear
• Enable passing structure value directly as parameter to .buzzmap() method (easier, if you don't use options)
• Maybe rename properties named obj ... They could eat your dog be more descriptive

Things already implemented:

• BUG: after editing a node without children it is made active (nodes without children can't get active) - finished
• general code review! - finished
• fix error (some nodes aren't affected by physics until you drag them) - finished
• CSS class for root node - finished
• More than one root node - finished
