re-adding sports proposal.
Competion -> Competition
refreshed with version from JasonJ.
Also removing the older def for memberOf
adding examples from sports doc.
Add RDFS for type and attribute pages

Includes properties such as:
* rdfs:comment
* rdfs:label
* rdfs:subClassOf

With this patch, individual type and attribute pages will now express basic
RDFS; classes will express their immediate subclass relationship and all
of the properties that can be applied to them, while attributes express
their domainIncludes values.

Clarify that RDFa and JSON-LD are supported formats

The getting started documentation referred to a long-term plan to
support a broader variety of formats, but RDFa and JSON-LD are
pretty tightly integrated into the rest of the schema.org documentation,
so we might as well mention them explicitly in the getting started (but
continue documenting with microdata as the default approach).

Removing bogus old files. Added a qa.html file for checking functionality after updates.
old version removed.
Removed index.yaml - leftover from previous versions that
used a persistent memory story.

Currently, everything is in memory.
whitespace.
Some initial tests, which go as far as making sure
we have examples and schema file, that schema file has XML-style balanced tags,
and that we can parse it, at least to the extent of finding a "Thing" unit.
Added some more introductory text.
Literal type doesn't exist in schema.org, it should be Text.

Bundle of tests to verify the core API.
Adding subproperty() and superproperty() methods on a unit node.
Also inverseOf() for property units, which will take care of looking
for the assertion in either direction, since it is symmetric.
Documented inverseOf and supercededBy properties, and moved Class and Property under Intangible where they belong.
Added tests for super/sub property relationships, and inverse properties.
Replaced assertEqual usage with assertTrue and assertFalse.
Now allows that we might have multiple sub-properties and super-properties.
Removed a mistaken reference to 'answer' property; this should have been suggestedAnswer.
Updated subPropertyOf accordingly.
Added subPropertyOf from Action-related properties that specialize 'participant'.
