>   ImportedString::ImportedString(TextChar* pChar,CXaraFileRecord* pRecord)

    Author:     Mark_Neves (Xara Group Ltd) <camelotdev@xara.com>
    Created:    14/8/96
    Inputs:     pChar   = ptr to a char node in the tree
                pRecord = ptr to string record that's been imported
    Returns:    -
    Purpose:    The constructor.

                pChar should point to a TextChar that's been inserted into the tree that contains
                the first character in the string.

                pRecord should point to the string record imported from the file.

                This constructor keeps a copy of the pChar address.
                It makes a copy of pRecord, so it's safe to delete pRecord after this call

    Errors:     -
