Support for N-dimensional image data

[curtis]

The current version of ImageJ is aware of five dimensions: X, Y, Z, time and channel. We would like for ImageJ to provide N-dimensional data modeling, to accommodate additional dimensions; e.g.:

• multiple types of channels simultaneously (e.g., emission wavelengths vs. excitation wavelengths)
• lifetime decay histograms
• cell polarization state (binary)
• screen/plate/well organization for high-content screening
• multi-field datasets

It should be possible to represent such data within imglib, but it would be nice to have at least one concrete example in code demonstrating how this should work.

ImgLib is N-dimensional. The updated ImgLib2 design will incorporate dimensional axis labels and units, to differentiate between dimensions.
