Hello world
=======================

Description
-----------

This example pretends to be a starting point to understand the functioning of P-Lingua and MeCoSim (custom apps, models, scenarios), along with a first approach to the modelling of **transition P systems** in P-Lingua.

Model in P-Lingua
-----------------

The corresponding P-Lingua code is the following::

	@model<transition>

        /* Transition P system model. */
        
        def main()
        {
                /* Membrane structure. */
                @mu = []'1;
                
                /* Initial multiset in membrane labelled by 1. */
                @ms(1) = a*1;
                
                /* Rules in membrane labelled by 1. */
                [a --> c]'1;
                [a --> b]'1;
        }

    * The example does not need input data from any user nor speficic interesting outputs, so it can be run from the `general app <https://github.com/luivalcab/MeCoSim-public-models/blob/master/001%20-%20General/ConfigFile_General.xls>`_ yet available and pre-loaded in MeCoSim.
    * `Model file <https://github.com/luivalcab/MeCoSim-public-models/blob/master/002%20-%20Hello%20World/Example1_HelloWorld.pli>`_, P-Lingua file with the code above.
    * As in the case of the app, no scenario file with specific input is needed, so the general dummy `scenario file <https://github.com/luivalcab/MeCoSim-public-models/blob/master/001%20-%20General/example1.ec2>`_ can also be used.
