12-Tone Dual-Tier "Nested" Morse-Thue Blues 16EDO Subscale

I came up with a better way to achieve the 12-tone 16EDO
Morse-Thue blues subscale last night using the process of
"nesting" (superimposing the prime and inversion forms of
a subscale in the minimum amount of pitch registral space).

The resulting 16EDO pitch classes used would be
1,3,4,5,7,8,9,10,12,13,14,16.

There is a 3-1-3-1-1-3-1-3 rotation of the 8-place
Morse-Thue sequence both ascending from pitch
class 1, and descending from pitch class 16.

It also has the identical spacing/key placement
of the 12EDO minor 3rd interval string ascending from
C1 (C1-D#1-F#1-A1-C2) and descending from
B1 (B1-G#1-F1-D1-B0) as well as the 12EDO
tritone ascending from C1 (C1-F#1-C2) and descending from
B1 (B1-F1-B0).

This particular form of the scale is also symmetrical.

I'll try and post a pitch-class/cents value diagram
later today.

So here's a Scala file for that
