Issue
Selecting live/dead cells using mouse drag (vs. clicking individual cells) is working, but when mouse is moved quickly not all cells in mouse path will change state.
Resolution
Investigate why this is happening, and seek solution such that all cells in mouse path (with mouse down) have their status changed and updated in the ui.

• Are changes being made to the grid in gameContainer state.currentGrid, but not rendering on screen?
• Or are changes not being triggered in in state.currentGrid, and this is being faithfully reflected in UI?

Investigate this and see if instances can be changed to strict inequality (!==).

Keys when mapping to be added. Use template string for unique key e.g. Row ${index} rather than just index.

Clean up unused imports

This seems to be similar issue to #5 .

Since the mouse clicks work, but with a delay, this suggests that issue here (as well as in #5) is due to slowness of either updating state, re-rendering, or both, rather than gameContainer.js state.currentGrid not being updated faithfully re: user input.
