Develop arcpy.mapping to support layer symbology modifications.
1. Changing fill (solid, patterned) stroke (solid, dashed etc), colour (rgb and cmyk input values), size, font properies of single symbol
2. Changing unique values, many fields symbology by selecting the field inputs, and symbology properties for each.
Also include colour ramp symbology.
3. MOST IMPORTANT!! Match symbols to a style!!!! Enable Value Field to be defined as well as .sty file location.
This will help improve and streamline production mapping.
