This component provides a server action to get diff lines information from two text lists.
The logic which is used in this component was ported from Tatsuhiko Kubo's implementations of "An O(NP) Sequence Comparison Algorithm."
https://github.com/cubicdaiya/onp

The core module has only one action.

DiffTextList

-> In1: Text List

-> In2: Text List

<- ses: Shortest edit script list

The ses is a list of record {Sign<Integer>, Text<Text>}.

• Sign 1: added item
• Sign -1: deleted item
• Sign 0: other
