Add a trieAlter method to TrieKey to replace the implementation of the alter function, and a corresponding gtrieAlter method to the GTrieKey class.
Use gtrieAlter to reimplement gtrieInsert and gtrieDelete for products. This avoids nested lookups followed by nested insertions/deletions, performing the whole modification in one pass.
