Add Working Build
Now the application is working as expected. Getting this to export a Fat JAR File was so tedious.

# Simple Calculator
2+
A simple calculator with the most basic of features made with Java 11 and JavaFX.
3+
4+
## Development
5+
The build tool is Maven and to build the package along with the cross-platform JAR, do `mvn package`.
6+
7+
## How To Use
8+
Just download the JAR file on the releases page of the repository and run it on your own Java Virtual Machine. On Windows, if Java is installed properly, simply double clicking on the JAR file would run it.
9+
10+
## Features
11+
This calculator application has a simple working GUI.
12+
- Basic operations such as addition, subtraction, multiplication, and division.
13+
- Clear all button which resets the calculator's state.
14+
- Sign button which changes the sign of the number positive to negative and vice-versa.
15+
- Rate button which changes the number to a rate.
16+
17+
## Possible Improvements
18+
Ofcourse, this application isn't perfect. Currently there is no keyboard input handling and thus, the experience doesn't feel too smooth. That could be a future feature.
19+
20+
