    /**
     * @class Ext.Template
     * Represents an HTML fragment template. Templates may be {@link #compile precompiled}
     * for greater performance.
     * For example usage {@link #Template see the constructor}.
     *
     * @constructor
     * An instance of this class may be created by passing to the constructor either
     * a single argument, or multiple arguments:
     *
     * single argument : String/Array
     *
     * The single argument may be either a String or an Array:
     * String :
    var t = new Ext.Template("<div>Hello {0}.</div>");
    t.{@link #append}('some-element', ['foo']);
     *
     * Array :
     * An Array will be combined with join('').

    var t = new Ext.Template([
        '<div name="{id}">',
            '<span class="{cls}">{name:trim} {value:ellipsis(10)}</span>',
        '</div>',
    ]);
    t.{@link #compile}();
    t.{@link #append}('some-element', {id: 'myid', cls: 'myclass', name: 'foo', value: 'bar'});

     *
     * multiple arguments : String, Object, Array, ...
     *
     * Multiple arguments will be combined with join('').
     *
    var t = new Ext.Template(
        '<div name="{id}">',
            '<span class="{cls}">{name} {value}</span>',
        '</div>',
        // a configuration object:
        {
            compiled: true,      // {@link #compile} immediately
            disableFormats: true // See Notes below.
        }
    );
     *
     * Notes:
     *
     * Formatting and disableFormats are not applicable for Ext Core.
     * For a list of available format functions, see {@link Ext.util.Format}.
     * disableFormats reduces {@link #apply} time
     * when no formatting is required.
