Enumerate a number of objects, or values

Using component_range or param_range , you can create enumerations of objects. Consider e.g. adding several Potentials to a single ExtPot_Hamiltonian: you use Potential_0, Potential_1, Potential_2, .... to create a list of Potentials. Syntax for Enumerations consist of a base name (Potential) followed by

• nothing: Create one single object or parameter
• a _ and a number, for an explicit enumeration
• _min, _max, and _N, to create a list of N doubles equally spaced between _min and _max
• _min, _step, and _N, to create a list of N numbers at _min, _min + _step, _min + 2*_step, ...
• _rand_min, _rand_max, _N, to create a list of N random numbers between _min and _max
