For this runner the _SLaMPipelineSourceInversion_ customizes:
- The _Pixelization_ used by the _Inversion_ of this pipeline.
- The _Regularization_ scheme used by of this pipeline.
The _SLaMPipelineSourceInversion_ use's the _SetupMass_ of the _SLaMPipelineSourceParametric_.
The _SLaMPipelineSourceInversion_ determines the source model used in the _SLaMPipelineLight_ and _SLaMPipelineMass_ pipelines, which in this
example therefore both use an _Inversion_.

__SLaMPipelineMassTotal__
The _SLaMPipelineMassTotal_ pipeline fits the model for the lens galaxy's total mass distribution.
A full description of all options can be found ? and ?.
The model used to represent the lens galaxy's mass is input into _SLaMPipelineMassTotal_ and this runner uses the default of an
_EllipticalPowerLaw_ in this example.
For this runner the _SLaMPipelineMass_ customizes:
- The _MassProfile_ fitted by the pipeline.
