More mods to work with CoalLog standard better.
(1) Have added in an option to specify the field (normally seam) that is placed on the graphics Log. With coallog some users prefer to use the Ply field. There is also an option to specify whether we are putting out the whole description or the equivalent output code.
(2) For the hatching. CoalLog standard has user entering coal as the Lithology and then specifying further in the "lith qualifier" field. For example an entry could be "Coal" and a qualifier as "Dull(1)"
Prolog if it finds Coal as a "Lithology" entry now checks whether there is a "Lith Qualifier" field. If so it adds the entrys together. Make sure you add in a new entry into the hatch file similar to below
