ACTOR STORY
1. There is a human executive actor as a user who uses a program as an assisting actor by an interface with inputs and outputs.
2. The program tries to construct a 2D-virtual world in the format of a grid. The program needs the size of the grid as
(m,n) = (number of columns, number of rows), which is here assumed by default as equal m=n. After the input the program
will show the grid on screen.
3. Then the program will ask for the percentage of obstacles 'O' and energy objects (= food) 'F' in the world. Randomly the grid
will be filled according to these values.
4. Then a finite number of virtual actors will be randomly inserted too. In the first version only one.
POSSIBLE EXTENSIONS
In upcoming versions the following options should be added:
1. Allow multiple objects with free selectable strings for encoding.
2. Allow multiple actors.
3. Allow storage of a world specification with reloading in the beginning instead of editing.
4. Transfer the whole world specification into an object specification. This allows the usage of different worlds in one program.

# SUPPORTING FUNCTION
#
# Now in a dedicated module gridHelper.py in folder 'code'
# Complete path: C:\Users\gerd_2\code
# This path has to be included for the python path search mechanism
#
# Show actual path values
#
# >>> import sys
#>>> sys.path
# ...
# Extend the python path by appending the modul path:
#
# In my case the path is as follows:
