/*
* Tab control.
*
* This plugin is a wrapper for the Twitter Bootstrap Tab component. It provides the following features:
* - Adding tabs
* - Optional close icons with 2 states (modified / unmodified). The icon state can be changed by
* triggering the modified.oc.tab/unmodified.oc.tab events on any element within tab, or on the tab itself.
* - Removing tabs with the Close icon, or with triggering an event from inside a tab pane or tab.
* The removing can be canceled if the confirm.oc.tab event handler returns false.
* - Scrolling tabs if they do not fit the screen
* - Collapsible tabs
*
* Data attributes:
* - data-control="tab" - creates the tab control from an element
* - data-closable - enables the Close Tab feature
* - data-pane-classes - a list of CSS classes to apply new pane elements
*
* Example with data attributes (data-control="tab"):
*
* <div class="control-tabs master" data-control="tab" data-closable>
* <ul class="nav nav-tabs">
* <li class="active"><a href="#home">Home</a></li>
* </ul>
* <div class="tab-content">
* <div class="tab-pane active">Home</div>
* </div>
* </div>
*
* JavaScript methods:
* - $('#mytabs').ocTab({closable: true, closeConfirmation: 'Do you really want to close this tab? Unsaved data will be lost.'})
* - $('#mytabs').ocTab('addTab', 'Tab title', 'Tab content', identifier) - adds tab. The optional identifier parameter allows to
associate a identifier with a tab. The identifier can be used with the goTo() method to find and open a tab by it's identifier.
* - $('#mytabs').ocTab('closeTab', '.nav-tabs > li.active', true) - closes a tab. The second argument can point to a tab or tab pane.
The thrid argument determines whether the tab should be closed without the user confirmation. The default value is false.
* - $('.nav-tabs > li.active').trigger('close.oc.tab') - another way to close a tab. The event can be triggered on a tab, tab pane
* or any element inside a tab or tab pane.
* - $('#mytabs').ocTab('modifyTab', '.nav-tabs > li.active') - marks a tab as modified. Use the 'unmodifyTab' to mark a tab as unmodified.
* - $('.nav-tabs > li.active').trigger('modified.oc.tab') - another way to mark a tab as modified. The event can be triggered on a tab, tab pane
* or any element inside a tab or tab pane. Use the 'unmodified.oc.tab' to mark a tab as unmodified.
* - $('#mytabs').ocTab('goTo', 'someidentifier') - Finds a tab by it's identifier and opens it.
* - $('#mytabs').ocTab('goToPane', '.tab-content .tab-pane:first') - Opens a tab in context of it's content (pane element)
*
* Supported options:
* - closable - adds the "close" icon to the tab and lets users to close tabs. Corresponds the data-closable attribute.
* - closeConfirmation - a confirmation to show when a user tries to close a modified tab. Corresponds the data-close-confirmation
* attribute. The confirmation is displayed only if the tab was modified.
* - slidable - allows the tabs to be switched with the swipe gesture on touch devices. Corresponds the data-slidable attribute.
* - paneClasses - a list of CSS classes to apply new pane elements. Corresponds to the data-pane-classes attribute.
* - maxTitleSymbols - the maximum number of characters in tab titles.
* - titleAsFileNames - treat tab titles as file names. In this mode only the file name part is displayed in the tab, and the directory part
* is hidden.
*
* Events:
* - beforeClose.oc.tab - triggered on a tab pane element before tab is closed by the user. Call the event's
* preventDefault() method to cancel the action.
* - afterAllClosed.oc.tab - triggered after all tabs have been closed
*
* Dependences:
* - DragScroll (october.dragscroll.js)
* - Toolbar (october.toolbar.js)
* - Touchwipe (jquery.touchwipe.min.js)
