This class provides the concrete implementation of the CMW enhanced expressions for the splitting function for .
The kernel uses the same overestimate as the corresponding HalfHalfOneSplitFn and thus only needs to implement the spitting function and ratio to the overestimate.
TODO: For a more efficient sampling one needs can rewrite the overestimation to contain the alpha_max*Kgmax factors.

Very similar to HalfHalfOneSplitFn. Here the kernel only contains the soft part multiplied by the alphas/2pi * Kg from Nucl.Phys. B349 (1991) 635-654

version | the version number of the object when written. |
void Herwig::CMWHalfHalfOneSplitFn::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
os | the persistent output stream written to. |

Since we use only the 1/1-z part for overestimating the kernel in the first place we can keep the same overestimation related functions for the CMW kernels.
