    """MeasureReset operation.

    This operation measures a qubit q, stores the value in a classical bit c,
    then applies a X operation to the qubit if the measured value is 1, effectively
    resetting the qubit to the |0> state.

    Examples:

        >>> from mimiqcircuits import *
        >>> c = Circuit()
        >>> c.push(MeasureReset(), 1, 0)
        2-qubit circuit with 1 instructions:
        └── MeasureReset @ q[1], c[0]
        <BLANKLINE>
        >>> c.decompose()
        init if -> operation= X
        2-qubit circuit with 2 instructions:

        └── IF(c == 1) X @ q[1], c[0]
