with parameterizations of n_phase and phase count, some general methods are summarized:

• move solution_expressions() to ComputationBase
• move extract_phase_results() to ComputationBase
• all tests passed

@haitao-ZCU Perfect, two small additions: make phases an attribute of the class so that it is not computed twice and make it work for a higher number of phases (such as 9), there is a small chance that we will need it later.

• move phases to init
• add to 11 phases
• update test_computation
• all tests passed
