Usage
#####

**Ex. Gather with column 1:**

Suppose we had the following table:

+---------+------------+-----------+
| Name    | Blood Type | Frequency |
+=========+============+===========+
| Bob     | A          | 4         |
+---------+------------+-----------+
| Jacob   | B          | 5         |
+---------+------------+-----------+
| Matthew | O          | 12        |
+---------+------------+-----------+
| Daniel  | AB         | 1         |
+---------+------------+-----------+

If we did a gather on column 1 creating a key column called "Key" and a value column called "Output"
we would get the following result.

+------------+-----------+------+---------+
| Blood Type | Frequency | Key  | Output  |
+============+===========+======+=========+
| A          | 4         | Name | Bob     |
+------------+-----------+------+---------+
| B          | 4         | Name | Jacob   |
+------------+-----------+------+---------+
| O          | 12        | Name | Matthew |
+------------+-----------+------+---------+
| AB         | 1         | Name | Daniel  |
+------------+-----------+------+---------+

----

**Ex. Gather with 2 columns:**

Same starting table

+---------+------------+-----------+
| Name    | Blood Type | Frequency |
+=========+============+===========+
| Bob     | A          | 4         |
+---------+------------+-----------+
| Jacob   | B          | 5         |
+---------+------------+-----------+
| Matthew | O          | 12        |
+---------+------------+-----------+
| Daniel  | AB         | 1         |
+---------+------------+-----------+

Now, if we specify the input columns as "1,2" to get columns 1 and 2 targeted as the key columns (called key),
we get the following output:

+-----------+------------+---------+
| Frequency | Key        | Output  |
+===========+============+=========+
| 4         | Name       | Bob     |
+-----------+------------+---------+
| 4         | Blood Type | A       |
+-----------+------------+---------+
| 4         | Name       | Jacob   |
+-----------+------------+---------+
| 4         | Blood Type | B       |
+-----------+------------+---------+
| 12        | Name       | Matthew |
+-----------+------------+---------+
| 12        | Blood Type | O       |
+-----------+------------+---------+
| 1         | Name       | Daniel  |
+-----------+------------+---------+
| 1         | Blood Type | AB      |
+-----------+------------+---------+
