Mike Gerwitz 0127d4b698 TAMER: sym::Interner::index_lookup
This was originally omitted because there wasn't a use case for it.  Now
that we're adding context to errors, however, an owned value is highly
desirable.

This adds almost no measurable overhead to the internment system in
benchmarks (largely within the margin of error).

Mike Gerwitz d97e53a835 [DEV-7084] TAMER: fs: Basic filesystem abstraction
This also includes an implementation to visit paths only once.  Note that it
does not yet canonicalize the path before visiting, so relative paths to the
same file can slip through, and relative paths to _different_ files could be
erroneously considered to have been visited.

This will be fixed in an upcoming commit.

Mike Gerwitz 400d5b25a1 ir::asg::Object::Empty: Remove variant
This variant is unnecessary, as it was used only by the indexer to represent
the absence of a node, for which was can simply use `None` in the containing
`Option`.

* tamer/Cargo.toml: Add `lazy_static`.
* tamer/Cargo.lock: Update.
* tamer/src/ir/asg/base.rs (with_capacity): Use `None` in place of
    `Some(Object::Empty)`.
* tamer/src/ir/asg/object.rs: Adjust state machine graphic.
  (Empty): Remove variant.
  (Missing): Remove reference to variance.
* tamer/src/lib.rs: Import `lazy_static` for test builds.
* tamer/obj/xmle/writer/writer.rs (Section::iter): Remove `Object::Empty`
    from documentation.
  (test::): Remove references to `Object::Missing`.  `lazy_static!` used
    here.
* tamer/obj/xmle/writer/xmle.rs (test::write_section_catch_missing): Replace
    reference to `Object::Missing`.

Mike Gerwitz bcc2ab1221 TAMER: Initial abstract semantic graph (ASG)
This begins to introduce the ASG, backed by Petgraph.  The API will continue
to evolve, and Petgraph will likely be encapsulated so that our
implementation can vary independently from it (or even remove it in the
future).

Mike Gerwitz a929c8cae4 TAMER: xmlo reader
This introduces the reader for xmlo files produced by the XSLT-based
compiler.  It is an initial implementation but is not complete; see future
commits.

Mike Gerwitz e4e0089815 TAMER: Initial string interning abstraction
This is missing two key things that I'll add shortly: a HashMap-based one
for use in the ASG for node mapping, and an entry-based system for
manipulations.

This has been a nice start for exploring various aspects of Rust
development, as well as conventions that I'd like to implement.  In
particular:

  - Robust documentation intended to guide people through learning the
    necessary material about the compiler, as well as related work to
    rationalize design decisions;
  - Benchmarks;
  - TDD;
  - And just getting used to Rust in general.

I've beat this one to death, so I'll commit this and make smaller changes
going forward to show how easily it can evolve.

(This module was originally named `intern` but this commit and those that
follow rewrote it to `sym`.)

Mike Gerwitz 8374541965 tamer: Initial baisc POC with no XML output
This is garbage code.  Do not use it.  It is intentionally throwaway.

While I've researched Rust, I haven't actually _used_ it for a project, so
this is a combination of me exploring various ways of accomplishing the
problem and forcing myself to learn certain aspects of the language.

I'll likely be using petgraph, and this also currently lacks symbol
abstractions.  This commit also performs far too much heap allocation
copying strings around.  But it _does_ perform the topological sort.

Since this only stores the symbol name, it lacks enough information about
the symbol to perform a proper linking.
