Function parity_matrix outputs a sparse matrix on some quantum codes and a full matrix on other codes.

In this package, I will not include Tableau struct. So for every code, I will only implement parity_matrix function.

Sounds good! Just make sure to have the parity_tableaux in QuantumClifford depend on the new parity_matrix when you have it.

As long as it is outputting AbstractMatrix of booleans, I think we are fine. The user can cast it to a specific type if they need it.

@Krastanov Basic settings(CI, test, docs and a few basic codes)for this package is done. After this version, all modification will be done through PR.

Thanks! Just FYI, I do not think package names like QECC.jl can be registered, so we might want to do something like QECCore.jl or QECBase.jl or QECCodes.jl (the last one exists as a repo here)
