Major changes:

• tensor units of extrusions
• layerings of extrusions on their fumulas
• extrusion hierarchy is now simpler and has a few new properties available

Minor changes:

• change subscripts to superscripts for names of properties, for consistency
• generalize extrusion direct products for different universe levels

Version 0.2.0: extrusions and constructions and more, oh my

Major new features

• fumula extrusions, the fumula-world counterpart to modules over rings
• construction of initial/terminal (almost) fumulas, direct products of (almost) fumulas, and identity and composition of (almost) fumula homomorphisms

Other changes

• the tripoint bracket operator _⤙_⤚_ is no longer infixl, and instead is just infix
• conversion of reversible fumulas to and from commutative rings
• fumula property names no longer have useless _s
• ●-◆-collapse-side{,ˡ,ʳ} have been moved out of the structures and into Properties, as they are derivable from the other axioms
• {↑-⤙⤚-●,↓-⤙⤚-■}-dup-nest{,ˡ,ʳ} have been introduced in Properties
• the heartline of a fumula (the shadow of the integers within it) is now available, with some theorems about it, in Properties
