object.

`e1` |
object to measure |

`bit` |
bit to project on |

`repetitions` |
number of measurements |

`measure(e1, bit, repetitions)`

performs `repetitions`

many
projections/measurements of the qubit `bit`

. If `bit`

is not given
explicitly, all qubits are projected.

`measure(e1, bit, repetitions)`

returns a list with the measured `bit`

,
the number of `repetitions`

, the probability distribution of all states
`prob`

and the results vector `value`

. If all bits are measured, the
basis is added to the list as `basis`

. The collapsed state is stored as
`psi`

if exactly one measurement is performed.
In the case of a single qubit measurement `value`

is of length `repetitions`

and contains all the results of this projection. Otherwise `value`

is of
length 2^nbits and it contains the counts how often each state has been
obtained.
