// This module contains only one function: LIInitialFocus.
// It will look for the control IDs as specified either in
// "initialIds" parameter or window.LIInitialFocusIds
// expando-property (if initialIds is not specified).
// As soon as a control is found, it will be focused
// and the function will return. If no control is found,
// no focus will be set.
//
// Function arguments:
// initialIds (optional): array of strings that specify
// IDs of page controls that should be focused when this
// function is run. Note that only the first found control
// will receive focus (not the remaining ones).
