// - Tools for CI(s) the "Configurable Information".
// - The CI presents the value wrapper for most of internal types and has
//   various reference and platform implementations like iOS native.
// - The UI packages xide,xblox,xideve and xfile and all their dialogs are generated by this type.
// - The widget class is mapped in CI['type'] which points to xide/types/ECIType, an
//   int enumeration from -1 = Unknown to at least 32 more values, after xide.types.ECIType.END begins
//   the user land

// - Urgent: the reason for value[0] in the code below is back-compate to pre Dojo - 2.0 stores. To be removed soon.
