Author: Murray Cumming <murrayc murrayc com>
Date:   Thu Jan 14 16:47:22 2010 +0100

    Rename get_stringstream_precision_default().
    
    * glom/libglom/data_structure/glomconversions.[h|cc]:
    get_stringstream_precision_default(): Rename this to the slighly-better
    named (because it's not mentioning implementation)
    NumericFormat::get_default_precision() in
    * glom/libglom/data_structure/numeric_format.[h|cc]: and document it
    vaguely.
