// # Semantic Modules
// This is a design pattern for creating ui modules in Semantic
//
// Semantic is unique in that all arbitrary data is a setting. Semantic modules also are self documenting, with module.debug calls serving to explain state, and log performance data.

// This is where the actual action occurs.

// It is necessary to include a settings object which specifies the defaults for your module

// Used in debug statements to refer to the module itself
name : 'Example Module',

debug : true,
// Whether extra debug content should be outputted
verbose : false,
// Whether to track performance data
performance : false,
// A unique identifier used to namespace events,and preserve the module instance
namespace : 'example',
// ### Optional
// Selectors used by your module
selector : {
example : '.example'
},
// Error messages returned by the module
error: {
noText : 'The text you tried to display has not been defined.',
method : 'The method you called is not defined.'
},
// Class names which your module refers to
className : {
disabled : 'disabled'
},
// Metadata attributes stored or retrieved by your module. `$('.foo').data('value');`
metadata: {
text: 'text'
},
// ### Callbacks
// Callbacks are often useful to include in your settings object
onChange : function() {},
// ### Definition Specific
// You may also want to include settings specific to your module's function
text: {
hover : 'You are hovering me now',
click : 'You clicked on me'
