[CMake] 2D arrays

[Robert Dailey]

I have created a pretty clean solution to this until there is native
support for multi-dimensional arrays in CMake. I have attached the module,
hopefully it will prove useful to others. Here is an example of how to use
it:

set( two_dee_array
apple cat
orange dog
banana elephant
)

array2d_begin_loop( advanced "${two_dee_array}" 2 "fruit;animal" )
while( advanced )
message( "Fruit: ${fruit}" )
message( "Animal: ${animal}" )
array2d_advance()
endwhile()
