Helper functions (bare vs. dressed basis)

Some of the helper methods available as part of the ParameterSweep class (see the API documentation for more details):

dressed_index obtain the dressed index corresponding to a bare index (use pre-slicing)

sweep["flux":0, "ng":0].dressed_index((1,0,1))

9

bare_index obtain the bare index (bare product state label) corresponding to a dressed index (use pre-slicing)

sweep["flux":0, "ng":0].bare_index(8)

(0, 2, 1)

energy_by_bare_index obtain the eigenenergy for given bare index (use pre-slicing)

sweep["ng":0].energy_by_bare_index((1,1,0))
