++ Added an error when reservoir is empty and should print an error message and exit.
 + Fixed some typo in output.
 + Fix a bug where seed number output and input was not the same size, so we changed int to uint while reading to avoid overflow. They both use uint now.
 + Increase memory allocation for NPT simulation in Ewald.
 + Fixed a bug in PickWeighted() function where it was return a value larger than the array.

 + Fixed a bug in MoveSettings where two for loops where not initialized.
 + Fixed a bug where in simulation of polar molecules, if any atom of the molecule has no VDW parameter (e.g. water), there is a chance that during insertion, atom of opposite charge will overlap and generate a very large energy value. Current mechanism of avoiding overlap is not working properly
