Initial commit of data model rewrite Ground-up rewrite of the data model. Putting this in the ve2 directory for now so we still have the old code floating around. Main changes so far in this rewrite: * Renamed hasChildren() to canHaveChildren() * Added canHaveGrandchildren() * Added a new node type TwigNode that can have children but not grandchildren (so all of its children must be LeafNodes) * Implemented push/pop/shift/unshift as wrappers around splice() * Renamed getElementType() to getType(). Nodes now take a string as a type, and the element stuff is gone and won't be back * Removed clearRoot(), replaced it with setRoot( this ) where needed Change-Id: I23f3bb1b4a2473575e5446e87fdf17af107bacf6 2012-04-19 20:54:34 +00:00			`/**`

Improved test coverage for ve.dm.BranchNode.splice and ve.dm.TwigNode.splice * Changed splice to check all elements about to be inserted are allowed before inserting any of them so that catching an exception leaves you in a sane state * Fixed the order of execution of parent class constructors in ve.dm.LeafNode and ve.dm.TwigNode so that canHaveChildren and canHaveGrandchildren produce correct values and added tests to ensure these methods are correctly inherited in subclasses * Added tests that check for exceptions when adding nodes that can have children to nodes that can not have grandchildren * Added test that check for events being emitted before and after splicing, including that beforeSplice should be emitted even in cases where a splice fails and throws an exception because the nodes are incompatible (but afterSplice is not called in this case) since beforeSplice might modify the nodes in some way before the compatibility tests are run Change-Id: Id12aea995a42c26ff63a74ae3d31f2bf455759e3 2012-04-20 00:45:58 +00:00			`ve.LeafNode.call( this );`
