Base language
Every scheme is assigned a base language (class) from the set of
possible ones. The base language class contains specific methods
for transforming the scheme, including sketchifying (converting
current plain sketchy text into structured sketchy text),
textualizing (converting current sketch into plain sketchy text),
and reducing (simplifying the structure of the current sketch).
Usually the primitive texts inside a sketch are written in corresponding
base language.
