Provide ability to look at oriented model in 1D cuts

[butlerpd]

Stephen King points out that for quick and dirty (and support the way people may be used to doing business) we could provide an oriented 1D fitting. In other words allow the option to fit a 1D slice (e.g. sector average) of an oriented pattern. This could be used as a wizard for setting up the 2D. Also we could use the 2D behind the scenes but integrate the result over the sector width (if that is available) which would then properly smear the model's orientation information to match the smeared 1D data.
