Devlog 2: Updated UI formatting, added project notes along with grading system, and updated Readme to match project’s core values.

Here is a snippet of the code for grading logic:

const DEFAULT_GPA_SCALE:  GPAScaleRule[] = [  
{ grade: "A+", points: 4.0, minPercent: 98},  
{ grade: "A", points: 4.0, minPercent: 93 },  
{ grade: "A-", points: 3.7, minPercent: 90 },  
{ grade: "B+", points: 3.3, minPercent: 87 },  
{ grade: "B", points: 3.0, minPercent: 83 },  
{ grade: "B-", points: 2.7, minPercent: 80 },  
{ grade: "C+", points: 2.3, minPercent: 77 },  
{ grade: "C", points: 2.0, minPercent: 73 },  
{ grade: "C-", points: 1.7, minPercent: 70 },  
{ grade: "D+", points: 1.3, minPercent: 67 },  
{ grade: "D", points: 1.0, minPercent: 60 },  
{ grade: "F", points: 0.0, minPercent: 0 },
];
