Reading Time!
I finally understood which logic structure we'll have -> wrote code and optimised it.
Then I began writing function to access that structure stored in file.
Wrote first half of it, tried to test - thus we have an adress in the "Options" panel, and a button that
executes reading function. Seems to work, though I don't have output and can't check that.
Fix it in next commit.
