And created "RunFilters" class within "Filtering" pacakage.

Currently RunFilters creates a new population by copying
only-non-freight agents from the input population into the output
population.

Intended use is for filtering freight agents out of the output_plans.xml
of fully relaxed simulations from the ASTRA-2018-002 project or that use
the synthetic population for Switzerland. The filtered_population.xml
would then at some point be simulated for one iteration, producing an
events file without freight agents. This is to give an SCCER group in
M-TEC at ETHZ a plans.xml and an events.xml for some electric-car vs
grid analysis that does not have freight, because they do not have the
contracts for it.

Update plotting for sensitivities

See merge request ivt-vpl/astra_2018_002!17

the cmap arrays were producing IndexError: index 3 is out of bounds for size 3 errors.

Set plot function to defaults and default colors allowed things to run.

so far I've been finding these methods via error messages.
IMPORTANT NOTE: I figured out that I need to alter "YEARS" and "AV_YEARS" and "SCENARIOS" to NOT include the years and scenarios that do not occur in the data set I'm feeding the code. Otherwise it still processes, say, 2040, and if there is no corresponding row, aka scenario, it returns an empty array or list or whatever and then that pesky "IndexError: index 0 is out of bounds for axis 0 with size 0" shows up.

because it won't work without explicitly coding them in, unfortunately

tried to add run_name to the methods that constructed filepaths, but so far unsucessfully

CAUTION: it just translates D to A and E to C, so make sure that you give this code, as input, aggregate.parquet files that only contain the data from one "series" of scenarios - aka one sensitivity analysis! Otherwise, it will probably spit out nonsense because it will have several pravAs and several pravBs and probably won't differentiate between them properly!

because we promised to test the 100% Avs with low PCUs on both ASTRA
Scenarios (normal car ownership aka A, and low car ownership aka B)

so that all freight agents use the mode truckAv when ASTRA_Scenario =
"D", when the person attribute "isFreight" is set to "true", the
selected plan of that person is modified such that all legs whose mode
was equal to "truck" are subsequently equal to "truckAv".

THIS HAS ONLY BEEN DONE FOR ASTRA_Scenario ="D", BECAUSE OTHERWISE THE
SENSITIVITY ANALYSIS FOR THE OTHER ASTRA SCENARIOS WOULD BE
INCONSISTANT!!

THUS, WHEN THIS CODE IS USED IN THE FUTURE THIS FIXED SHOULD BE APPLIED
TO THE OTHER PARTS OF THE FREIGH ASSIGNMENT IF LOOP!
