Upgrade: iOBE Calculator v2.1

The upgrades in iOBE Calculator v2.1 are:

1. The size of the main window panel of this software has been resized into a smaller input console. The console only contains the push-buttons to initiate computations and tabs to input/display text. In the previous versions, the main window is a fixed-size input/output panel containing these buttons, tabs, and six output graphs; these made the window size too large to be displayed in laptops with small screens.
2. The software is able to compute data for all class sizes, including small classes of 2 to 5 students (except for a class with 1 student). Previously, the software were not able to compute data for small class of 5 students or less.

The input console is shown below, with the same buttons and tabs as in the previous versions:

The outputs are displayed as graphs in two separate windows (as shown below) and as text files to display their numerical values. The graph-windows are now resizable (compared to the windows of the previous vesions, which had fixed sizes). Users can easily change the window size according to their needs.
