Remove GettingStarted.m and enhance sweep.m documentation

- Deleted the GettingStarted.m file as it is no longer needed.
- Updated the sweep.m function documentation to provide a clearer description of its purpose, input parameters, and an example usage.

+# Animator Documentation
+
+*Last updated: December 19, 2024*
+
+## Overview
+
+Animator is a specialized MATLAB® toolbox designed to create GIF animations from MATLAB code. It provides a powerful yet simple way to visualize parameter changes in your MATLAB plots by automatically generating animated GIF files.
+
+## Key Features
+
+- Parameter sweep automation
+- Smooth transition generation
+- GIF file creation
+- Support for reverse animations
+- Customizable frame rates
+- Integration with MATLAB editor
+
+## Requirements
+
+- MATLAB R2022a or newer
+- MATLAB Editor (for code manipulation)
+- Write permissions in the working directory (for saving GIF files)
+
+## Core Functions
+
+### sweep.m
+
+The main function that handles the animation creation process. 
+
+**Syntax:**
+```matlab
+sweep(filename, codeLine, sweepRangeText, lineNumber, nSteps, animationOption, reverseFlag, saveAnimFlag, gifFileName, framesPerSecond)
+```
+
+**Parameters:**
+- `filename`: The target M-file containing the plot code
+- `codeLine`: The line of code containing the parameter to animate
+- `sweepRangeText`: Range specification for the parameter sweep
+- `lineNumber`: Line number in the file to modify
+- `nSteps`: Number of steps in the animation
+- `animationOption`: Animation style option
+- `reverseFlag`: Boolean to control bi-directional animation
+- `saveAnimFlag`: Boolean to control saving to file
+- `gifFileName`: Output GIF filename
+- `framesPerSecond`: Animation frame rate
+
+### splitCode.m
+
+Utility function for parsing code lines and extracting variable information.
+
+**Supported Code Formats:**
+- Simple assignment: `a = 1`
+- Complex expressions with numerical values
+
+## Usage Guide
+
+1. **Prepare Your Code**
+   - Create an M-file with your plotting code
+   - Identify the parameter you want to animate
+   - Ensure the parameter is assigned a numerical value
+
+2. **Set Animation Parameters**
+   - Choose the sweep range for your parameter
+   - Decide on the number of animation steps
+   - Set the desired frame rate
+   - Choose whether to include reverse animation
+
+3. **Generate Animation**
+   - Call the sweep function with your parameters
+   - The tool will automatically:
+     - Modify your code
+     - Generate plot snapshots
+     - Compile the GIF animation
+
+## Best Practices
+
+1. **Code Organization**
+   - Keep plotting code in a separate section
+   - Use clear variable names
+   - Comment your animation parameters
+
+2. **Performance Optimization**
+   - Choose appropriate step counts
+   - Consider frame rate impact on file size
+   - Use efficient plotting commands
+
+3. **File Management**
+   - Use descriptive GIF filenames
+   - Save animations in a dedicated directory
+   - Keep backup copies of original code
+
+## Troubleshooting
+
+Common issues and solutions:
+
+1. **Line Doesn't Match Expected Assignment**
+   - Ensure the target line contains a simple numerical assignment
+   - Check for proper syntax in the assignment statement
+   - Verify line number is correct
+
+2. **Animation Quality Issues**
+   - Adjust number of steps for smoother transitions
+   - Modify frame rate for better viewing
+   - Consider using the reverse flag for smooth looping
+
+3. **File Access Problems**
+   - Check write permissions in the target directory
+   - Ensure file paths are correct
+   - Verify MATLAB has access to all required files
