#230 Create metrics summary files

[lueFlake]

As in #230, added steps/summarize.sh step which generates csv reports in 'data/summary/{metric}.csv'. Used this structure of csv:
repository,count,sum,average,mean,min,max

@lueFlake looks very good, but where is the test? How do you know that it works?

[lueFlake]

@yegor256 I tested it in a local environment, working on tests rn

[lueFlake]

@yegor256 added tests, task is basically done

i'd like to add more flexible summarization (for now every summary contains only a certain number of aggregations). By "flexible" i mean adding new directory (smth like "summary_aggregations/") in the root where i put scripts which aggregate metrics in different ways (i call them "aggregations" but i mean things like sum, average, mean of a metric).

Also here is an example of script working on cam-2021-07-08.zip, it's a part of LOC.csv

@lueFlake try to give this file a more complicated name, for example:

echo "50" > "${dir1}/file1 -p (test ) \n?.m.LOC"

@lueFlake would be better to define a variable $repo and then use it everywhere, instead of the repo1 literal. Also, try to give it a more complicated name, like a.x/b-one

@lueFlake same here, the file name is too simple, it doesn't really help us reveal possible errors in the script

@lueFlake looks great! see a few comments above

@yegor256 can you review the code? I resolved your comments

[yegor256]

@lueFlake thanks!
