    Creates a tuple containing (line, column) by calculating line number
    and column in the text, from position.

    The position represents the index of a character. In the following
    example 'a' is at position '0' and it's corresponding line and column are:

    >>> calc_line_col(('a\n',), 0)
    (1, 1)

    All special characters(including the newline character) belong in the same
    line, and have their own position. A line is an item in the tuple:

    >>> calc_line_col(('a\n', 'b\n'), 1)
    (1, 2)
    >>> calc_line_col(('a\n', 'b\n'), 2)
