ENH: connection_test.f90 renamed to connection_mem_leak_test.f90 along with its binaries and rewritten to serve only as a binary file for Valgrind check. Its former use as unit test is now adopted by FUnit .fun files.

NEW + ENH: Added new module normal_m to generate random numbers from Gaussian distribution + simplified CMakeLists.txt

FIX + ENH: Fixed parameter for turning on/off time profiling. Fixed constructors and destructor in connection_m module. Added missing comments into connection_m module.

ENH: Module 'connection_m' was cleaned up, so the dummy Neuron class was moved to the separate module 'neuron_dummy_m'.

ENH: Added Makefiles and Connection module separated into two file - one with module itself and the other one for testing purposes.

ENH + FIX: Added comment to multiple methods + fixed constructor implementation for the class IntervalConnection.

    contains:
        - module Connection_mod with classes Connection and
          IntervalConnection

    TODO:
        - delete dummy Neuron class after its implementation
        - fully comment the code
