Change subject: Merging and remapping
......................................................................
Merging and remapping
Add merge() methods to IndexValueStore and InternalList, which merge
another store/list in to the current one and return a mapping
translating old indexes to new ones.
Also add functions that, given such a mapping, traverse a linear
model data array and remap store/list indexes using simple logic for
annotations and node type-specific functions for node attributes.
