Create chess interface

[Kruhlmann]

To start with the site needs to have a board that can be properly interacted with. Piece SVG files are available in the static folder.

Green dots representing legal moves should be shown on a separate overlay:

• Analysis arrows etc.
• Legal moves/captures
• Pieces (SVG)
• Chess board

From first visible to last.

The expected output from a functions, which finds moves for a string is a list of moves in the following format:

{
    origin: "f2",
    destination: "f3",
    meta_data { ... }, // Data about this move (win rates, frequency etc.)
}

We don't yet know what the metadata object will hold.
