Nodes of different colours represent the following:
Solid arrows point from a submodule to the (sub)module which it is
descended from. Dashed arrows point from a module or program unit to
modules which it uses.

flag
flag that identifies which case the solution is
- 0: 3 real rotos, one of them repeated (use real_roots(1) and real_roots(2))
- 1: 1 real root, 2 complex roots.
Use real_roots(1) and complex_roots(1) and complex_roots(2)
- -1: 3 real roots, all different
Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed
arrows point from an interface to procedures which implement that interface.
This could include the module procedures in a generic interface or the
implementation in a submodule of an interface in a parent module.
