React-Grid-Layout-Enhancement is a grid layout system modified by React-Grid-Layout, for React.

change log:

1.add layout change reason

add ChangeReason in utils.js:
export const ChangeReason = {
  didMount: "didMount",
  didUpdate: "didUpdate",
  dropItem: "dropItem",
  containerWidthChange: "containerWidthChange",
  itemMove: "itemMove",
  itemResize: "itemResize"
};

modify onLayoutChange func:
onLayoutChange(changeReason, layout, newLayouts)

so that developer can know the reason why onLayoutChange fired

2. lock width and height radio for ResponsiveReactGridLayout when window size changed

u can add isLockWidthAndHeightRadio={false} props to ResponsiveReactGridLayout to disable this function
