Workspace Method doit_conv_flagAbs

Description

DOIT convergence test (maximum absolute difference).

The function calculates the absolute differences for two successive
iteration fields. It picks out the maximum values for each Stokes
component separately. The convergence test is fullfilled under the
following conditions:
   |I(m+1) - I(m)| < epsilon_1     Intensity.
   |Q(m+1) - Q(m)| < epsilon_2     The other Stokes components.
   |U(m+1) - U(m)| < epsilon_3   
   |V(m+1) - V(m)| < epsilon_4   
These conditions have to be valid for all positions in the
cloudbox and for all directions.
