Columnize - format an Array as a Column-aligned String
============================================================================

In showing a long lists, sometimes one would prefer to see the value
arranged aligned in columns. Some examples include listing methods of
an object, listing debugger commands, or showing a numeric array with data
aligned.

Setup
-----

    use Array::Columnize;
    print columnize(['a','b','c','d'], {displaywidth=>4});

produces:

    1  3
    2  4

With numeric data
-----------------

    $data_ref = [80..120];
    print columnize($data, {ljust = 0}) ;

produces:

    80  83  86  89  92  95   98  101  104  107  110  113  116  119
    81  84  87  90  93  96   99  102  105  108  111  114  117  120
    82  85  88  91  94  97  100  103  106  109  112  115  118

while:

    print columnize($data_ref, {ljust = 0, arrange_verticle = 0}) ;

produces:

    80  83  86  89  92  95   98  101  104  107  110  113  116  119
    81  84  87  90  93  96   99  102  105  108  111  114  117  120
    82  85  88  91  94  97  100  103  106  109  112  115  118

With String data
----------------

    @ary = qw(bibrons golden madascar leopard mourning suras tokay);
    print columnize(\@ary, {displaywidth => 18});

produces: 

    bibrons   mourning
    golden    suras   
    madascar  tokay   
    leopard 

    puts columnize \@ary, {displaywidth => 18, colsep => ' | '};

produces:

    bibrons  | mourning
    golden   | suras   
    madascar | tokay   
    leopard
