Renaming for descriptiveness (#29)

* add example for the paper * rename params in MpsParameters * rm MPSAnnealing, ctr.beta is now a scalar instead of a vector * clean up * clean up * clean up * kwargs in SingleLayerDroplets * clean up * rename * new branch from paper * change version * bump version --------- Co-authored-by: Bartek <[email protected]> Co-authored-by: Łukasz Pawela <[email protected]>

 In the boundary MPS-MPO approach we apply Matrix Product Operator (MPO) to appropriate sites of Matrix Product State (MPS). In this context, the absorption of a MPO into a MPS leads to an exponential growth of the bond dimension. Hence, a truncation scheme is necessary to mitigate this issue and to keep the bond dimension in a reasonable size. 
 Our package offers users the flexibility to choose between three distinct methods for optimizing the boundary MPS used in contracting the tensor network: 
 * `Zipper`
-* `MPSAnnealing`
 * `SVDTruncate`.
 `Zipper` method combines randomized truncated Singular Value Decomposition (SVD) and a variational scheme.
