Detailed description

This class implements a "policy" template for bidirectional path tracing: all bidirectional path tracing kernels are templated over a TBPTConfig class that must implement this interface. In order to change the policy, it is sufficient to inherit from this class and override the methods. Note that the methods are not virtual, but the code is written so as to use the implementation of the last class that overrides them, mantaining the inlining efficiency.
