Explain Snowball and Napoleon's points of view about building the windmill in the beginning of chapter five.

After some time, Snowball and Napoleon come into bitter conflict over a windmill. Snowball designates a piece of land for a windmill, which will provide electricity for the heretofore-primitive farm. He uses Mr. Jones’s books to draft a detailed chalk blueprint, which fascinates the other animals. One day, Napoleon urinates on the blueprint to show his disdain. Napoleon probably thinks the windmill is a good idea but, because it comes from Snowball, he is against it.
