Data2D stores no information about the shape/dimensionality of the data

[lewis]

The Data2D object currently stores 2D data as three 1D arrays (data, qx_data and qy_data)

This is an issue when it comes to plotting the data, since the 1D data array needs to be converted into a 2D array, but the Data2D object has no information about what shape the 2D array should be.

It's also an issue when it comes to writing NXcanSAS files, since the data is written to the file as a 2D array.

The Data2D object does actually store information about the shape of the data in x_bins and y_bins, there was just a bug in cansas_reader_HDF5.py that x_bins and y_bins weren't being set.

However, there is still an issue that PlotPanel.py doesn't seem to know about these properties, so creates it's own bins based on the assumption that the data is square.

Also, when we looked yesterday with Andrew, it wasn't clear that DataInfo? was being fed the size/shape.
