Removed the unnecessary template parameter in class template WangLandau::Parameters. Introduced a copy constructor to initialise from a Parameter class from another Wang-Landau simulation (does compile if the energy types and the histo types can be converted.)
Modified the wang landau example program to fit to the new non-template wang landau parameters.
Modified the histograms to be able to convert histograms with different, but convertible x_value_type into each other.
Merge branch 'master' of https://github.com/bkrueger/mocasinns
Harmonized the parameters for the algorithms that sample the density of states. Closes #41
Renamed [get_]density_of_states -> [get_]log_density_of_states. Closes #39
Added vector energy and tests to mocasinns library.
Included the array energy type.
* Used SFINAE to be able to use step types that do not define is_executable or selection_probability_factor, because they use them trivially.
* Added a do_generic_steps function in the simulation base class that tooks two template bool parameters and uses default parameters for is_executable and selection_probability_factor if they are not defined.
Closes #27
Changed the copy constructor of SpinLattice to set explicitly the extension of the new array, because copying boost::multi_arrays can fail if the two arrays do not have the same shape.
Introduced output stream operators for spins and lattices of spins of dimension 1 and 2.
Extended the test routines for the equality operator of spin lattice
Included the possibility to convert parameters of the entropic sampling from parameters of other entropic sampling simulations if the corresponding types can be converted.
Fixed minor bug (forgot to add the template parameter in calling another member function) in parallel metropolis.
Added histogram observables (will mainly be used for analysing various density of states)
* Included a typedef for the container of the pointers to the neighbouring spins into each class of spin network.
* Small modifications of the documentation of the spin network
A newly discovered bin in the Wang Landau algorithm will now be initialised with the minimal density of states.
Closes #21
