NAME: idl2cdftype PURPOSE: Given an IDL variable, return the appropriate CDF type code CALLING SEQUENCE: code = idl2cdftype(var, format_out=format_out, fillval_out=fillval_out, validmin_out=validmin_out, validmax_out=validmax_out) INPUT: var = an IDL variable OUTPUT: code = the CDF data type code for that variable, if applicable, for objects, complex, and similar vars a null string is returned.
