Same name and namespace in other branches

1. 7 color_field.module \color_field_field_formatter_view()

Implements hook_field_formatter_view().

Three formatters are implemented.

• color_field_default_formatter just outputs markup indicating the color that was entered and uses an inline style to set the text color to that value.
• color_field_css_declaration does the same but also changes the background color or color of a region defined by the selector.
