Table

java.lang.Object
- processing.data.Table

```
public class Table
extends java.lang.Object
```
Generic class for handling tabular data, typically from a CSV, TSV, or other sort of spreadsheet file.

CSV files are comma separated values, often with the data in quotes. TSV files use tabs as separators, and usually don't bother with the quotes.

File names should end with .csv if they're comma separated.

A rough "spec" for CSV can be found here.

    Set the titles (and if a second column is present) the data types for this table based on a file loaded separately. This will look for the title in column 0, and the type in column 1. Better yet, specify a column named "title" and another named "type" in the dictionary table to future-proof the code.
    
    Parameters:
