Map commands in .vimrc to align Cucumber complient Feature File steps on the space after the keywords:

" Use Tabularize to set shortcute `,as` to align on feature file step keywords
let mapleader=','
nmap <Leader>as :Tab /^\W*[Given\|When\|Then\|And][a-zA-Z]*\zs\W/r0c0l0<CR>
vmap <Leader>as :Tab /^\W*[Given\|When\|Then\|And][a-zA-Z]*\zs\W/r0c0l0<CR>

So this:

Feature: VIM Tabularize Align Example

Scenario Outline: Tabularize can align steps
    Given I have a foo
    When I do bar
    And bar responds
    Then the bar response has <resp-obj>
    And the bar response is successful

    Examples: Bar Responses
    | resp-obj |
    | baz      |
    | egg.     |
    | spam.    |

Becomes this:

My regex-fu is weak, so this can almost certainly be optimized and improved
