Electrodynamics can be computed with traditional vector calculus or as Alan shows with newer generalized methods of geometric algebra. Prasoon's work last year was to develop a general vector calculus package and a then to make use of this core for the existing mechanics package and the new electrodynamics package. If you want to have a nice electrodynamics package I'd suggest these possible paths:
1. Complete the vector calculus package so that we have high quality general vector calc tools, then build your package on top of that. 2. Learn geometric algebra and build your package on top of that. One nice thing about geometric algebra is that it isn't confined to 3 spacial dimensions. Traditional vector calc has limitations in this regard, but is what most people know and for most engineering problems the 3D issue is not a major concern. If fact, I'd like to bring geometric algebra into the fold in the mechanics package, as it is the basis of more modern dynamics methods, such as the ones presented by Jain and Featherstone.
