Implement state structure #150

In this section, I learned tips on using state to avoid bugs. Some principles to solve the above problem are:

If two state variables always update together, merge them into one
Avoid contradictions in state
Avoid redundant states
Avoid duplication in state
Don't put props into state
For UI patterns like selection, keep id or index in state
If deeply updating nested state is complicated, try flattening it: Instead of a tree-like structure where each place has an array of its child places, each place holds an array of its child place IDs.
