co_clustering: spatial and time coherence using Kmeans.

[romulogoncalves]

To plot spatio-temporal coherence in a single map we need to build a matrix k*L where each cell has the average value for all for the cells and years of the indice value.

A easy method to get such matrix might be: KxM * MxN * NxL

The other solution is to assign the co-clusterID to each MxN cell and then select on co-clusterID and use the selected cells as mask to get the average of the resulting matrix.
