All automata were readapted and are in accordance with the last description of the thesis. Tests passed

check_constraint and update_state functions are created inside
create_automaton_*(), by the evaluation of meta_elementary_functions <:
Expr. check_constraint and update_state don't depend on constants::Dict
anymore: constants are interpolated inside the expression.

Add of tests for euclidean distance automaton.
Add a new function euclidean_distance that computes the euclidean
distance of a Trajectory compared to observations along a discrete
timeline.

- A_per (period_automaton) computes noisy period of an oscillatory model
- A_eucl (euclidean_distance) computes euclidean distance with regard to
data points of a trajectory.

1 script that plots oscillatory trajectory is added

automata and proba moels are differents. This bug was introduced after
we change the structure of automata in order to better distributed
programming.
It leads to a restructuration of automata. In fine, the structure is
more stable and consistent. It is possible it is more computationally
efficient, but for now it is not well tested.

2) Creation of functions that collects data along with a timeline
over a trajectory + unit test vectorize.

3) Very small fix in plots and abc smc.

1) LHA now have names. 2) Period automaton executes well and was runned on the doping 3way oscillator model. Not stattistically tested yet

Simulation of synchronized models is easily distributable.
Change of the signature of check_constraints and update_state in order
to access the model parameters.
Test about distributed simulations was renamed and completed.

now the package has a better structure for distributed simulations by better definition of functions over workers + test

Change of signatures of unit functions update_state!, check_constraints
of the automata edges. Use getfield instead of getproperty.

Now the execution of statistical estimation of the distance G is of the
order of Cosmos !

Reimplementation of easy access / modifications of StateLHA fields for better performance. Tests passed

Replaced access of fields in models with getfield. Improvement of distribute_mean_lha_value: number of accepts are computed simultaneously.3

Fix in simulation of macro generated models. Small changes with variables types of the pkg. Small change in test of macro models.

models. It's a better semantic and improve performance as well as
readability of the code. All the tests passes (except the remark in the
last commit).
