*
* To satisfy requirements of managing items of type other than a `String`, different implementation

* initialization like so:
*
* $('#input').textext({

/**
* TextExt provides a way to pass in the options to configure the core as well as
* each plugin that is being currently used. The jQuery exposed plugin `$().textext()`
* function takes a hash object with key/value set of options. For example:
*
* $('textarea').textext({
* enabled: true
* })
*
* There are multiple ways of passing in the options:
*
* 1. Options could be nested multiple levels deep and accessed using all lowercased, dot
* separated style, eg `foo.bar.world`. The manual is using this style for clarity and
* consistency. For example:
*
* {
* item: {
* manager: ...
* },
*
* html: {
* wrap: ...
* },
*
* autocomplete: {
* enabled: ...,
* dropdown: {
* position: ...
* }
* }
* }
*
* 2. Options could be specified using camel cased names in a flat key/value fashion like so:
*
* {
* itemManager: ...,
* htmlWrap: ...,
* autocompleteEnabled: ...,
* autocompleteDropdownPosition: ...
* }
*
* 3. Finally, options could be specified in mixed style. It's important to understand that
* for each dot separated name, its alternative in camel case is also checked for, eg for
* `foo.bar.world` it's alternatives could be `fooBarWorld`, `foo.barWorld` or `fooBar.world`,
* which translates to `{ foo: { bar: { world: ... } } }`, `{ fooBarWorld: ... }`,
* `{ foo : { barWorld : ... } }` or `{ fooBar: { world: ... } }` respectively. For example:
*
* {
* itemManager : ...,
* htmlWrap: ...,
* autocomplete: {
* enabled: ...,
* dropdownPosition: ...
* }
* }
*
* Mixed case is used through out the code, wherever it seems appropriate. However in the code, all option
* names are specified in the dot notation because it works both ways where as camel case is not
* being converted to its alternative dot notation.
