Daru::DataFrame#verify

Test each row with one or more tests. Each test is a Proc with the form
*Proc.new {|row| row[:age] > 0}*

The function returns an array with all errors.

FIXME: description here is too sparse. As far as I can get,
it should tell something about that each test is [descr, fields, block],
and that first value may be column name to output. - zverok, 2016-05-18
