This example demonstrates the use of the predefined external procedures in SDL.

The behavior consists in reading the contents of "file_1.txt", writing them in "file_2.txt",
and displaying them in order and reverse order in the same radar graph (simulation only).

1. Simulation (using "file_1.txt" and "file_2.txt" in "MyFilesSimulation")
Execute "MySystem" with "Simulation" profile, and then run the simulation.
When done a graph will be shown with the results, and "file_2.txt" will have 
the contents of "file_1.txt" and some info about its total number of lines.

2. Code generation (using "file_1.txt" and "file_2.txt" in "MyFilesCodeGeneration")
Execute "MySystem" with either "Linux" or "Windows" profile, and run debugger.
When done "file_2.txt" will have the contents of "file_1.txt" and some info 
about its total number of lines.
Note that graphs are not available in this case.
