Implement Editing feature

[catchmareck]

Functionalities:

• Ability to customize the renderer responsible for the cell view in edit mode by providing a new class (by default we display a text input).
• Ability to conditionally block edit mode - the 'editable' option should accept either a boolean or a function that returns a boolean based on some condition.
• Value parser - the ability to transform the edited value (e.g., string => number).
• Value setter - the ability to incorporate custom logic responsible for saving the edited value.
• Row/cell edit mode - the ability to choose to edit the entire row or just a single cell.
