Removed 'network' argument from the setter and getter.
Major changes to the setter and getter arguments.

From now on, each object can only write to itself.
Using fluid setter for all the fluid modules.

'network' setter has been removed.
Some changes to the algorithm modules based on the new setter and getter.

The main change is removing of 'phase' arguments from them.
Minor change in setter arguments.

Other modes will be added soon. I removed some of them, because they
would not work as we expected. After minor changes in the logic, I'll
add them.
