search-and-replace

Experiment. Don't use this.

TODO

• Create grammar, similar to markdown so that I can fold and jump by cmd-r.
• Open with adjacent pane
• Dynamically add grammar matching with search keyword to achieve highlight(using marker make editor slow maybe).
• update result text start from line3 onDidChange first line.
• Ignore other line change
• On save, update corresponding text-buffer.
• Keep update result-buffer -to- actual-buffer to be translatable
