    Default Ext.ux.ComponentQuery

    Hi All

    I have been going through the classes we have developed over the last few years and sharing back with the community some of them that I think will be useful to others. These components have been tested extensively in ext-3.2.1.

    Here is: Ext.ux.ComponentQuery

    A singleton used to search for components and execute javascript on them.
