This function will load the Collection from the directory specified by
the "Name" argument. If the target that "Name" points is a directory
that is readable by the current user and contains a valid Collection
specification (either in native or in GATE format), then this
Collection will be loaded from disk to the memory. A new Collection
object (of type CDM_Collection) will be created and returned to the
caller.
Return Value:
This function will construct and return a Collection object (of type
CDM_Collection) that will represent the Collection stored at the
directory specified by the "Name" parameter. The caller must use this
object in order to refer to the newly opened Collection and must use
the function tip_Close in order to close the Collection and free the
occupied memory if the Collection is not needed any more.
In case of an error an error message will prompt.
