Simple CSV Editor for Godot

Simple CSV Editor is a plugin for you to edit/view/csv files inside the Godot editor.

Originally I wanted to make something that can allow me to change a few values in a CSV file quickly without leaving Godot. It has expanded with the ability to create new files, and basic row/column creation. 

Features:

• Backup original files to pre-defined directory*. Can be disabled.
• Can check if first column values are unique
• Can generate running ID number for first column

Notes:

• The first row is assumed to be the header and contain the column names.
• Created files are .txt resources
• Files can only be loaded/saved to res://
• Delimiter is the humble comma.
• Commas in data are encoded into a string, and decoded when read.**
• Saved/New files take several moments to show their saved contents inside the Godot editor. If you open them in notepad etc, you'll see the files are indeed correct. Just give the Godot editor a few seconds to catch up.
• using .txt so don't need to fuss with the import settings of .csv files

* can be changed by altering constant in .gd file
** likewise, is a constant and can be changed in the panel.gd file
