Reaction Toolkit Introduction:

New object type: Transformation.

• Very similar to a pattern. Limited access to its component nodes.

• Created with dt_trxin(string, mapstring). (Analogous to dt_smartin()). This will change in 4.51 release (map part of transform string).

• Primary use: dt_transform(txf, mol, direction, limit). Returns one or more reactions.

• dt_pattern(txf) returns underlying pattern (guaranteed to match any reactions created using dt_transform()).
