A table of Rationals

We are going to implement a method

  String tableOfRationalsMarkdown(int rows, int cols) { ...

This method will produce a table such as this one for the call:

Rational.tableOfRationalsMarkdown(3,4)

Numerators

| |1|2|3|4|
|-|-|-|-|-|
|1|1|2|3|4|
|2|1/2|1|3/2|2|
|3|1/3|2/3|1|4/3|

When rendered as Markdown, that looks like this:

	1	2	3	4
1	1	2	3	4
2	1/2	1	3/2	2
3	1/3	2/3	1	4/3

But what we'd really like to be able to do, is select how the numbers are formatted in a flexible way.

For example, I'd also like to get a table like this one:

	1	2	3	4
1	1.000	2.000	3.000	4.000
2	0.500	1.000	1.500	2.000
3	0.333	0.667	1.000	1.333
