it calls LDLDecomposition, a function to decompose symmetric p.s.d. matrices.
Instead it should call a slightly different function, for Hermitean p.s.d. matrices (which are not symmetric, but
equal …

The primary goal of this ticket is to improve the creation speed for the quantum Bruhat graph. We do this in a number of ways:
- Better management of data associated to `lattice.nonparabolic_positi…

Calling `abs()` on certain expressions can yield something which is not guaranteed to be evaluated as a real number:
```
sage: abs(x^2)
x*conjugate(x)
sage: abs(x)^2
x*conjugate(x)
```
