Write grid attribute
writeAttr(gridID,attrname,data)
writeAttr(gridID,attrname,data) writes
an attribute to a grid. If the attribute does not exist, it is created.
If the attribute exists, it can be modified in place, but it cannot
be recreated with a different data type or length.
This function corresponds to the GDwriteattr function
in the HDF-EOS library C API.
