+/* SELFSIZINGTABLE
+ *
+ * An ANSI text-display oriented table, whose column widths conform to width of
+ * their contents. The goal is to optimize whitespace usage, so there's neither too
+ * much nor too little whitespace (e.g. min. necessary for optimal readability).
+ *
+ * Contents can only be added to and redisplayed, not manipulated after adding.
+ *
+ * Simple API (see example below):
+ *
+ * 1. Create table instance.
+ * 2. Add column definitions.
+ * 3. Add each row and set data for each column in a row.
+ * 4. Invoke the displayTable() method.
+ *
+ * Each time the table is [re]displayed its contents are [re]evaluated to determine
+ * the column sizes and header and data padding.
+ *
+ * Example:
+ *
+ * SELFSIZINGTABLE tbl(2);
+ * void *colPlanet = tbl.addCol("Planet" "%s", 1);
+ * void *colInhabit = tbl.addCol("Inhabitability", "%-12s = %s");
+ *
+ * // This is an 'unrolled loop' example. More typical would be to iterate,
+ * // providing data content from arrays, indicies, in-place calculations,
+ * // databases, etc... rather than just hardcoded literals.
+ *
+ * void *row = tbl.addRow();
+ * tbl.setCell(row, colPlanet, "Earth");
+ * tbl.setCell(row, colInhabit, "Viability", "Decreasing");
+ * row = tbl.addRow();
+ * tbl.setCell(row, colPlanet, "Mars");
+ * tbl.setCell(row, colInhabit, "Tolerability", "Miserable");
+ * row = tbl.addRow();
+ * tbl.setCell(row, colPlanet, "Neptune");
+ * tbl.setCell(row, colInhabit, "Plausibility", "Forget it");
+ *
+ * tbl.displayTable();
+ *
+ * Planet Inhabitability
+ * Earth Viability = Decreasing
+ * Mars Tolerability = Miserable
+ * Neptune Plausibility = Forget it
+ *
+ * (note:
+ * Column headers displayed in bold red to distinguish from data)
