NestedList - typo

[LesJ]

I'm pretty sure there's a typo in the doc: hierarchial --> hierarchical

Is hierarchial a word?

Some wiseacre wrote a bug fix for my software saying hierarchical was the only spelling of the word and I'd like to prove said wiseacre wrong.

Ext.define('Ext.dataview.NestedList', {
    ...
    /**
     * @cfg {Ext.Component} detailCard provides the information for a leaf
     * in a Miller column list. In a Miller column, users follow a
     * hierarchial tree structure to a leaf, which provides information
     * about the item in the list. The detailCard lists the information at
     * the leaf.
     *
     * See http://en.wikipedia.org/wiki/Miller_columns
     *
     * @accessor
     */
    detailCard: null,
    ...
