This is perhaps the second simplest sampler - it simply takes all its samples from a list in a file and runs them all with the new pipeline.
This could probably be replaced with an importance sampler, and may be merged into it in future.
Installation
No special installation required; everything is packaged with CosmoSIS
Parameters
These parameters can be set in the sampler’s section in the ini parameter file. If no default is specified then the parameter is required. A listing of “(empty)” means a blank string is the default.
