First draft of DANCE

Description language for ANalog Circuit Engines (DANCE) is another
scripting language for analog engines. In contrast to AESL, which is
focused on connectivity of the engine, it is rather focused on user
readability and simplicity. Thus realizing the connections requires more
effort than with AESL.

Example: TP1 07.19 Falling Mass

+# FallingParticle, VERSION 20240225
+# Calculate the deflection from the vertical caused by the Earth's rotation of a particle falling freely from rest from a height h.
+# Differential Equations:
+#    x''=-bz'+ay' # x-axis is along latitude,  directed to east
+#    y''=-ax'     # y-axis is along longitude, directed to north
+#    z''=-g+ax'   # z-axis is perpendicular to the surface of earth
+#    g: gravitational acceleration = 9,81 m/s²
+#    a: 2*omega*sin(phi)
+#    b: 2*omega*cos(phi)
+#    omega: rotation velocity of the earth = 2*pi/day
+#    phi: Latitude of location (0-90°)
+#    Initial Condition: z(0)=h
+# The full solution requires 6 INTEGRATORs, Anabrid-THAT just has 5. The deflection to longitude (y) is neglegible and can be omitted (marked #*).
+# It could also be solved in a separated algorithm omitting x.
