Specialization patterns
=======================
Since we are reasoning in a spatial logic, when eliminating a lemma or
hypothesis of type
``P_0 -
★ ... -★ P_n -★
R``
, one has to specify how the
hypothesis of type
``P_0 -
∗ ... -∗ P_n -∗

hypotheses are split between the premises. The proof mode supports the following
_specification patterns_
