Features:

[X] Code for counting piecewise constant components of a 1D and 2D array
[X] Tests for components counting
[ ] Add conditioning variable verifications (Linear, linear-reciprocal, quadratic)
[ ] Add tests for conditioning variable verifications
[x] Add conjugacy rules
[ ] Add tests for conjugacy rules
[ ] Add regression test for full hierarchical model with TV

@nabriis , within the _get_conjugate_parameter method _conjugate.py, an error is raised when the same parameter is found multiple times. Is there any particular reason for raising this error and not just returning a list to loop over? Because for the RegularizedGaussian and ModifiedHalfNormal conjugacy pair the parameter will occur twice.
