Add C++ code generation and test scenario (#310 )

* add parameters to byzantine send action

* make net not trusted

it's not necessary since for proofs Ivy will assume that the environment
does not break action preconditions

* use require instead of assume

it seems that assume is not checked when other isolates call!

* add comment

* add comment

* run with random seed

* make domain model extractable to C++

* substitute require for assume

assumes in an action are not checked when the action is called! I.e.
they place no requirement on the caller; we're just assuming that the
caller is going to do the right thing. This wasn't very important here
but it leade to a minor inconsistency slipping through.

* make the net isolate not trusted

there was no need for it

* add tendermint_test.ivy

contains a simple test scenario that show that the specification is no
vacuuous

* update comment

* add comments

* throw if trying to parse nset value in the repl

* add comment

* minor refactoring

A few improvements to the Ivy proof (#288 )

* Avoid quantifier alternation cycle

The problematic quantifier alternation cycle arose because the
definition of accountability_violation was unfolded.

This commit also restructures the induction proof for clarity.

* add count_lines.sh

* fix typo and add forgotten complete=fo in comment
