* The objective of this program (which consists of 3 java files including
* this one, is to group a number of gridlets with small MIPS ratings into 
* a gridlet group according to the MIPS rating of a specific Grid resource,
* and send the gridlet group to that Grid resource for the execution purpose.
*
* This class takes input parameters from the user, creates virtual resources
* and invoke "Test" class for simulation.
