Version 0.14.0

"Dotting the t's and crossing the i's" edition:

Bugfixes:

• setup.py: macros are not zip safe, because ZipImporter fails to return source code for the module and MacroPy needs that.
• fix splicing in the do[] macro; ExpandedDoView should now work correctly
• fix lambda handling in the lazify macro
• fix dict_items handling in mogrify (fixes the use of the curry macro with code using frozendict)

New:

• roview: a read-only view into a sequence. Behaves mostly the same as view, but has no __setitem__ or reverse.
• mg: a decorator to mathify a gfunc, so that it will m() the generator instances it makes.
• The do[] macro now supports delete[name] to delete a local variable previously created in the same do-expression using local[name << value].
• envify block macro, to make formal parameters live in an unpythonic env.
• autoref block macro, to implicitly reference attributes of an object (for reading only).

Breaking changes:

• The macropy3 bootstrapper now takes the -m option; macropy3 -m somemod, like python3 -m somemod. The alternative is to specify a filename positionally; macropy3 somescript.py, like python3 somescript.py. In either case, the bootstrapper will import the module in a special mode that pretends its __name__ == '__main__', to allow using the pythonic conditional main idiom also in macro-enabled code.
• The constructor of the writable view now checks that the input is not read-only (roview, or a Sequence that is not also a MutableSequence) before allowing creation of the writable view.
• env now checks finalization status also when deleting attrs (a finalized env cannot add or delete bindings)

Non-breaking improvements:

• env now provides also the collections.abc.MutableMapping API.
• The tco macro now skips nested continuations blocks (to allow Lispython in Pydialect to support continuations).
• setup.py now installs the macropy3 bootstrapper.
