React Calendart component

• Based on older component that had major internal entanglement of different domains. Core logic and UI rendering was tightly coupled.
• This is version with separation of conserns:
  • Bussiness logic as data-structures
  • Rendering that took data-structures and render information
  • Styling (CSS)

GOALS

• Simple Calendar component that has abstract API for fetching and saving data. Currently just save into LocalStorage.

TODO

• Base refactor version is done.
• Need to form more responsive page layout and something that not just break in major browsers.
• Default date is empty and point into browser default (1970s)
• Focus to addition tools when click a day-cell
• Change months
