function  ckdtype(variable, datatype1, datatype2, datatype3, datatype4)

%CHKDTYPE Checks if the variable has any of a list of allowed datatypes.
%
%--------
%Synopsis:
%  ckdtype(variable, datatype1)
%  ckdtype(variable, datatype1, datatype2)
%  ckdtype(variable, datatype1, datatype2, datatype3)
%  ckdtype(variable, datatype1, datatype2, datatype3, datatype4)
%
%Description:
%  Checks if the variable has any of a list of allowed datatypes and
%  if not issue an error message.
%
%Output and Input:
%  variable (Any type): Variable to test.
%  datatype1 (StringT): First allowed data type.
%  datatype2 [D](StringT): Second allowed data type.
%  datatype3 [D](StringT): Third allowed data type.
%  datatype4 [D](StringT): Fourth allowed data type.
%
%--------
%Notations:
%  Data type names are shown in parentheses and they start with a capital
%  letter and end with a capital T. Data type definitions can be found in [1]
%  or by "help dbtdata".
%  [D] = This parameter can be omitted and then a default value is used.
%  When the [D]-input parameter is not the last used in the call, it must be
%  given the value [], i.e. an empty matrix.
%  ... = There can be more parameters. They are explained under respective
%  metod or choice.
%
%Known Bugs:
%  Only the following datatypes are checked:
%    RecVarT, StringT.
%  Vector of DoaT is partially checked.
%  Variables of all other data types are allowed regardless of the "datatype1"
%  input parameter.
