Remove the requirement to implement "meas[...]" gates. Instead, they are renamed "basis[...]" gates, and defined automatically using a Hermitian eigendecomposition (so when gate("basisX") is called, an eigendecomposition of gate("X") is performed by default, but a user can overload gate("basisX") if they want).
Replace "prepX+" gates with a new inputstate("X+") interface.
New interface qubits(N, ["X+", "Y-", "Z+"]) for making a product state in an arbitrary basis. The function uses the new inputstate definitions, such as inputstate("X+").
Change the randomstate/randomprocess insterface for selecting the element type. This remove the complex keyword argument. Instead, the element type is passed explicitly as the first argument, i.e. randomstate(Float64, 4). By default, randomstate(4) = randomstate(ComplexF64, 4), as before.
Rename the randomstate/randomprocess keyword argument init to alg for choosing the algorithm for generating the random tensors (which right now are "rand" or "circuit").
Change randomstate/randomprocess to default to having dimension 1 links and purified indices.
Rename getsamples keyword argument inputstates to local_inputstate and localbasis to local_basis.
In getsamples, always sample from a random Pauli basis ["X", "Y", "Z"] by default.
This makes the following changes:
