* Fields are texts attached to a symbol, some of which have a special meaning.
* Fields 0 and 1 are very important: reference and value.
* Field 2 is used as default footprint name.
* Field 3 is used to point to a datasheet (usually a URL).
* Fields 4+ are user fields. They can be renamed and can appear in reports.
