A part of a diagram
The part entity takes the id of an element of the SVG file as its first
argument, and its at option gives the steps that show that element.
Expresso.Element.Diagram gives the rules.
A copy entity of a part goes into copies. Expresso.Element.Copy.expand/1
gives each copy its own part, with the source in copy_of and the target in
copy_to. A copy of a copy has the target of its source in copy_start.
In a formula, each names a symbol and within names the part that holds
its occurrences. With bare, the base of a symbol with an index is not an
occurrence. Expresso.Element.Math.Each gives the occurrences the class of
the part. The copy of a link between the lines of a formula has covers, and it hides its
target.
