Gieb an input parameter name (such as that in a table.params file) search a file parlabs file to extract the parameter label for that quantiy. This routine is used in make_parlabs to build a parlabs file for a corresponding params file. If the quantity is not present in the input parlabs file or is the parlabs file is not present, then then the name of the input parameter is listed twice on output (i.e. the label text string is the same value as the name of the parameter). Note that this is a very minimilast routine in that it has no "--help" or debug option.

This routine, especially in concert with make_parlabs can be used to perform a lot of other jobs. For example, we could extract parameter values for a configuration file.
