LensAgent has a prototoypes class variable this needs to be part of the reset fixture
added fixture for 20 PUs (this is what the lens in files work with)
write unit test for seed agent no update using LensAgent_20 fixture
delete commented out code
pep8 doc string
comments and partial docstring for seed_agent()
lens .in files for training and updating, taken from mdme

the training file is not 20 units, and takes an env, c for the criterion
commented out unused variable

probably artifact from a previous refactor
added criterion to the seed_agent function and 'c' to the env for LENS
added criterion to update state functions to set env, 'c'
call lens using -batch instead of -nogui
comments
reset_lens_agent_20 calls reset_lens_agent before assigning 20 unit prototype
fix move and fix test_create_weight_file so it is tested before the seeds
reset seed agent no update with 20 PU
fix seed function, but needs a way to seed the RNG

Need a way to seed LENS in #8 to have a deterministic unit test
unit test update agent
