Raster build

[ktoddbrown]

I know we've talked about switching to raster instead of an array as our default build I thought I would lay out some of the main advantages and disadvantages of this.

Pro:

1. Dynamic read of data into memory.
2. Reads data from multiple files nicely.

Con:

1. Can not deal with non-rectangular grids.
2. Does not write nicely to ncdf(4), loses dimension names.

At this point I think that being unable to deal with non-rectangular grids is a killer for the package.

I agree, and am closing this (for now at least).
