- * One way in which we make it simpler to build an ETableModel is through
- * the ETableSimple class.  Instead of creating your own ETableModel
- * class, you simply create a new object of the ETableSimple class.  You
- * give it a bunch of functions that act as callbacks.
- * 
- * You also get to pass a void * to ETableSimple and it gets passed to
- * your callbacks.  This would be for having multiple models of the same
- * type.  This is just an example though, so we statically define all the
- * data and ignore the void *data parameter.
- * 
- * In our example we will be creating a table model with 6 columns and 10
- * rows.  This corresponds to having 6 different types of information and
- * 10 different sets of data in our database.
- * 
- * The headers will be hard coded, as will be the example data.

-/*
- * There are two different meanings to the word "column".  The first is
- * the model column.  A model column corresponds to a specific type of
- * data.  This is very much like the usage in a database table where a
- * column is a field in the database.
- *
- * The second type of column is a view column.  A view column
- * corresponds to a visually displayed column.  Each view column
- * corresponds to a specific model column, though a model column may
- * have any number of view columns associated with it, from zero to
- * greater than one.
- *
- * Also, a view column doesn't necessarily depend on only one model
- * column.  In some cases, the view column renderer can be given a
- * reference to another column to get extra information about its
- * display.
