Example
>>> from chord_chart import ValidationError, transpose_chart, validate_chart

>>> # | *chord-with-accidental-and-symbols* |
>>> validate_chart('| A/E E | E | \n| C#m|')
'| A/E E | E |\n| C#m |'
>>> validate_chart('A/E E\nC#m') # and that's not a valid one: chords without stripes between lines of bars
