interactivePlot

[AlexJamesWright]

The old interface I used to make plotting easier is outdated and doesn't work with the new file format. I will update this to work with both formats, probably stealling some things from Ian's plotting. Any features that anyone would like, list them below. For a start, I think plotting final data should be like accessing data in numpy format. For time series data, indexing would probably be easier through the slice index, but should be able to access the slice by providing a simulation time too (defaulting to the slice with the closest time to the one requested). Want to provide iterators for looping throught the slices too.
