</span> * A mixin which allows a component to be configured and decorated with a label and/or error message as is
* common for form fields. This is used by e.g. Ext.form.field.Base and Ext.form.FieldContainer
* to let them be managed by the Field layout.
*
* NOTE: This mixin is mainly for internal library use and most users should not need to use it directly. It
* is more likely you will want to use one of the component classes that import this mixin, such as
* Ext.form.field.Base or Ext.form.FieldContainer.
*
* Use of this mixin does not make a component a field in the logical sense, meaning it does not provide any
* logic or state related to values or validation; that is handled by the related Ext.form.field.Field
* mixin. These two mixins may be used separately (for example Ext.form.FieldContainer is Labelable but not a
* Field), or in combination (for example Ext.form.field.Base implements both and has logic for connecting the
* two.)
*
* Component classes which use this mixin should use the Field layout
* or a derivation thereof to properly size and position the label and message according to the component config.
* They must also call the {@link #initLabelable} method during component initialization to ensure the mixin gets
* set up correctly.
