A class that allocates unique sympy symbols for integrating out bloq attributes.

qualtran.resource_counting.SympySymbolAllocator()

When counting, we group bloqs that only differ in attributes that do not affect resource costs. In practice, we do this by replacing bloqs with a version where the offending attributes have been set to an arbitrary (but unique) symbol allocated by this class. We refer to this process as “generalizing”.
