Explain why we need YAGrid

[sebastienjust]

Explain in a few words why we needed YAGrid, including

• need for a style-free component
• do not depend on any other framework than react
• strong typing system
• plugin architecture
• for apps with hundreds of tables that need to be industrialized
• editing table data as a very strong feature based on type system
• separate view from data, especially for data rendering and editing needs
• do not always match columns to data
• externalized data (the component does not manage the data itself)
• not relying on components for state management
• better error management
• etc.
