This function merges the different local operators together to a PushType instance (See DmrgTypedefs.h for the type definition.). This pushlist is used for the construction of the Mpo.

Parameters
B: Base class from which the local operators are received
P: The parameters
pushlist: All the local operators for the Mpo will be pushed into pushlist.
labellist: All the labels for the Mpo will be put into labellist. Mpo::generate_label will produce a nice label from the data in labellist.
boundary: Boundary condition. Either BC::OPEN, BC::PERIODIC or BC::INFINITE.
