Detailed Description

template<class Integration_policy>
class BubbleProfiler::Perturbative_profiler< Integration_policy >

Bounce solver using perturbative method.

This is the main interface class for the BubbleProfiler. The workflow for using this class is as follows:

Specify the domain size and discretization parameters via the set_ methods.
Supply a Profile_guesser class via set_initial_guesser to generate an initial ansatz solution.
Supply a Profile_convergence_tester via set_convergence_tester to determine the stopping critera.
Call calculate_bubble_profile to perform the calculation. Callers of this method supply:
- A scalar field potential (Potential).
- An algorithm for solving the ODE which determines the perturbative corrections (BVP_solver).
- An Observer to monitor the output.
Retrieve the resulting Field_profiles via get_bubble_profile.
