Feature Request: return parsed variables

[markhalliwell]

Create a feature that allows you to parse a less document and return set variables in an array. This would be useful when trying to create a theme file that has predefined constants

Example:

@color1: #ff0000;
@Color2: #0000ff;

would return:

array(
'color1' => '#ff0000',
'color2' => '#0000ff',
)
