Removed the long range selfexcitation.
Removed all unused currents etc from code.
Removed the weighting functions, writing them directly into the ODEs.
Cleaned the main file for compilation testing.
Changed the effect of intrinsic currents. They are no scaled with
respect to the membrane time constant as they are assumed to be
insantaneous.
Made a function for the synaptic currents.
Removed the scaling of input noise.
