#setup_config(config) ⇒ Object

Internal: setup layout configuration and setup the default layout of form, you can change it in a particular row.

config - layout config, default nil, it must be a hash.

:layout      - it's a string ,specify the scale of columns.
               for example: '1:1', '1:2', '1:1:1'
:spacing     - left and right padding of form, should be number or percentage.
:label_width - label width of input, should be number or percentage.
:max_width   - max width of form, should be number or percentage.

All width options should be all numbers or all percentages, or it will not
be calculated correctly.

I'm looking for a method to provide responding design. Any contribution will be
appreciated.
