Subject: ee: o Adding FactType as a smaller wrapper around the fact uri. o
 Adding ee.part.Facts, used as Part.facts o Renaming 'type' uri to
 'ee-component-type'. kicad-make-bom: Removing strategy functionality,
 replaced with part-apply-function. Moving default strategy contents into
 ee.kicad.functions.
