/**
 * Description:
 *
 * A Seven Segment Display is an electronic display device, used
 * to display decimal or hexadecimal numerals. It involves
 * seven led segments that are lit in specific combinations
 * to represent a specific numeral. An example of
 * each combination is shown below:
 *
 * seven segment display
 *
 * For this Kata, you must accept an integer
 * in the range 0 - 999999 and print it as
 * a string (in decimal format), with each digit being
 * represented as its own seven segment
 * display (6x seven segment displays in total). Each of
 * the individual led segments per display should be
 * represented by three hashes ###. Vertical bars | (ASCII 124)
 * represent the edges of each display, with a
 * single whitespace on either side between the edge and the
 * area of the led segments. An example of the
 * expected output is shown below:
 *
 * segment_display(123456) =
 *  |  ###  |  ###  |       |  ###  |  ###  |
 *  |     # |     # |     # | #   # | #     | #     |
 *  |     # |     # |     # | #   # | #     | #     |
 *  |     # |     # |     # | #   # | #     | #     |
 *  |       |  ###  |  ###  |  ###  |  ###  |  ###  |
 *  |     # | #     |     # |     # |     # | #   # |
 *  |     # | #     |     # |     # |     # | #   # |
 *  |     # | #     |     # |     # |     # | #   # |
 *  |       |  ###  |  ###  |       |  ###  |  ###  |
 *
 *
 * For clarity, the entire set of required combinations is provided below:
 *
 *  |  ###  |       |  ###  |  ###  |       |  ###  |  ###  |  ###  |  ###  |  ###  |
 *  | #   # |     # |     # |     # | #   # | #     | #     |     # | #   # | #   # |
 *  | #   # |     # |     # |     # | #   # | #     | #     |     # | #   # | #   # |
 *  | #   # |     # |     # |     # | #   # | #     | #     |     # | #   # | #   # |
 *  |       |       |  ###  |  ###  |  ###  |  ###  |  ###  |       |  ###  |  ###  |
 *  | #   # |     # | #     |     # |     # |     # | #   # |     # | #   # |     # |
 *  | #   # |     # | #     |     # |     # |     # | #   # |     # | #   # |     # |
 *  | #   # |     # | #     |     # |     # |     # | #   # |     # | #   # |     # |
 *  |  ###  |       |  ###  |  ###  |       |  ###  |  ###  |       |  ###  |  ###  |
 *
 *
 * If the number is smaller than 6 digits, the result
 * should be justified to the right, with the
 * unused segments being blank (as they are not turned on).
 * Refer to the sample test for an example.
 *
 *
 * Note: There should not be any trailing whitespace for any line.
 *
 * Please rate and enjoy!
