[Rock-dev] Matrix as properties

[Chris Mueller]

Alternatively, you can also use /std/vector<double> for defining a fixed 
Matrix and
it only needs a small convertion for aligning all elements from the 
vector to the fixed matrix.

Though i'm currently working much on NEXT, this was quite comfortable 
especially using the ports
on the ruby and yaml side, where you can use Array Literals for math. 
matrices and vectors like e.g.:

matrix = [1, 0, 0,
                 0, 1, 0,
                 0, 0, 1]

Don't know if something similar is applicable on MASTER.

Surely, this rather a workaround for that, but it would avoid 
modifications in the base/orogen/types.

Not sure if it's recommanded; I've have only seen that in another orogen 
package, which uses intensively
many matrix vector configurations with different dimensions and it was 
quite useful in that moment.
