The Hilbert Curve is one of the earliest FASS-curves. The original algorithm in [hil1891]
bases on one substitution rule and an additional rule which describes how the substitutes have to be connected.
As briefly mentioned in [pau2021]
it is also possible to create the Hilbert Curve by a substitution tiling with two substitution rules and appropriate decorations.
The inflation factor `$q$`

is 2 and the lines are shifted slightly away from the center of the sides to illustrate the matching rules.
