/*
This is a test for the network builder functions. It has three parts:
First Net1.inp is loaded, run and the head for Tank 2 at the end of the simulation is recorded (h_orig).
Then, Net1 is built from scratch using the net builder functions (EN_init, EN_addnode, EN_addlink....).
The built network is then run and the the final head of Tank 2 is recorded again (h_build).
In the last stage, the built network is saved to an INP file which is reloaded and runs. Again the final
head is recoded (h_build_loaded).
The test ends with a check that the three head values are equal.
