Source code for aperta.errors

"""Aperta-specific exception types.

These are raised from across the library when an error condition is specific
to aperta (rather than a generic Python error like `ValueError`). Catching
these by type lets calling code distinguish aperta failures from upstream
library failures or programming bugs.
