Refactor viewers

[wd15]

Refactoring the viewers requires the following: - integrate Open DX - create base viewing class - it should contain most of the common functionality such as interpolation that needs to be done in FiPy. - enable unstructured mesh viewing - simplify pyx viewer - allow gnuplot to display variables

Logged In: YES user_id=121894 Viewer factory class/method? Should be able to say &view this variable& without worrying about which viewers the user has installed, or what dimensions of mesh are, etc. Factory class does the inspection necessary to produce an appropriate Viewer. If you want a specific viewer, import and instantiate it; if you just want a viewer that works, use the factory. Where does functionality lie to do interpolation for different mesh geometries? No interpolation in the viewers. If you have an unstructured mesh and you want to display it on a structured viewer, create an intermediate variable with a structured mesh and plot that; let it interpoloate. Viewer should be simple. Sole function is to take data from our CellVariable/Mesh format and turn it into whatever format that a viewing package can handle. Some viewers, e.g., gist will only be able to display structured mesh variables; others, e.g. dx, could do structured or unstructured. Not realisitic to add plot() parameters for all the possible things somebody might want to customize their view with. Use the viewer's capability to use template files or scripts (gist, Igor, gnuplot? can all do this). Either specify the template by name or pass in a preformatted script.

Logged In: YES user_id=121894 Process started. Call fipy.viewers.make(vars = ???) to get a functional viewer. Only works with Gist, but architecture is sound.

Logged In: YES user_id=121894 Now works with a variety of viewers. PyX has been removed in favor of matplotlib. FIPY_VIEWER environment variable allows specifying desired viewer.
