Comprehensive test cases and analysis of fog contributions to the global allocation table

[skmonga]

During the running of ElfStore on D20 setup, some issues were observed wherein some of the quadrants had negative values for allocations. This was caused due to the usage of Math.ceil() instead of Math.floor(). The bug fixes were done, we need to add more comprehensive test cases to address the corresponding bug fixes.

Need to do comprehensive analysis of all the 9 cases where a fog fits in the global storage and reliability matrix. Conditions which should be true in every case are :

• sum of all four quadrants in the global matrix is equal to the total number of edges in the system
• no negative value in any quadrant also a reduction in value one quadrant should accompany an increase in the value of another quadrant.
