107 Apps Script: Google Sheet CRUD

The following is a minified version of the previous tutorials:
1) Select records from Google Sheet.
2) Add new records into Google Sheet.
3) Edit records in Google Sheet.
4) Delete records in Google Sheet.
5) Search records in Google Sheet.

The codes are for learning purpose. 
They have not been extensively tested for robustness yet.

Use at your own risk :-D
