### Understanding CSV Format

#### P7.5

The CSV (or **comma-separated values**) format is commonly used for tabular data. Each table row is a line, with columns separated by commas. Items may be enclosed in quotation marks, and they must be if they contain commas or quotation marks themselves. Quotation marks inside quoted fields are doubled. 

For example, consider the following line with four fields:

```
1729, San Francisco, "Hello, World", "He asked: ""Quo vadis?"""
```

#### Programming Project

Create a `CSVReader` program that reads a CSV file and implements the following methods:

- `int numberOfRows()`
- `int numberOfFields(int row)`
- `String field(int row, int column)`

### Explanation

This task involves developing a CSV reader capable of handling typical CSV formatting complexities, such as embedded commas and quotes within fields. The methods defined will allow the reader to interactively query the structure of the data and retrieve specific information from the dataset.
