On the "free_grid" function there was a bug when dealing with Purkinje network, the program
could not be finished correctly.
On "vtk_polydata_grid.c" file the name of the datatype to be saved was set to "realcpu_32"
instead of "Float32".
3) Upgrades:
Add a description and more comments for the usage of "calc_APD.py" script.
Add a new script to plot several action potentials in one single axis
("plot_multiple_potentials.py").
Add a new program in the scripts folder to calculate and dump the positions (x,y,z) of every single cell in the grid to a file.
("cell_positions_calculator")
Add a new program in the scripts folder to calculate the propagation velocity between two cells in the grid.
