pySCG: providing building blocks in context with sign, encrypt, key-handling

[myteron]

We decided in decision 0022 during CWE-502: De-serialization of Untrusted Data) that we don't want partial explanations for an overall solution to sign, encrypt, key-handling in individual rules.

Instead we either want to create of find a introduction to how security can work in Python explaining 'building block' on the road to overall security including trust zones and trust relations.
