Add a note in the README about ongoing development
Merge remote-tracking branch 'origin/develop' into develop
Add wildcards to perf tests
Fixup ast module to remove multimatch typechecks

Instead of using SubExpression(Field, WildcardIndex),
the ast is now ElementsBranch(Field).  Similarly for
wildcards on a dict.
Centralize multimatch logic to multimatch class

That way each new node does not have to explicitly worry
about how to deal with multimatch types.
Remove unused import
pep8 formatting
Allow wildcard indices to exceed bounds

If any of the indices in a wildcart match don't generate
an index error, we should be returning a list of any matching
indices.  Previously, if any of the lists generated an index error
we'd return a None value.
Add more tests for indices
Merge branch 'better-ast' into develop
