Display N-dimensional data tables (with color highlighting)

Legible display of N-dimensional data tables with color highlighting of entries.

DisplayTable offers many more options than Matlab's built-in matrix display functions, when it comes to matrices/tables that are 3+ dimensional.
DisplayTable prints out a space-saving, legible N-dimensional table of numeric data including:
* dimension (row and column) labels and headings
* specified cell spacing and precision
* display dimensions in any order by specifying an output permutation!
* highlight cells with any colors you want, using the cprintf function (also on Matlab Central)! Note: cprintf relies on undocumented Matlab features.

Sample call:

displaytable(rand(5,5),{'1' '2'},{{'C1' 'C2' 'C3' 'I1' 'I2'},{'C1' 'C2' 'C3' 'I1' 'I2'}})

Will display:

1/2 C1 C2 C3 I1 I2
C1 0.76 0.71 0.82 0.44 0.49
C2 0.74 0.03 0.69 0.38 0.45
C3 0.39 0.28 0.32 0.77 0.65
I1 0.66 0.05 0.95 0.80 0.71
I2 0.17 0.10 0.03 0.19 0.75
