Better surface syntax. Closes #34
...
* Unified the surface syntax. There are no longer distinctions between
single-arity and multi-arity function/function types.
* Removed case and case*, in favor of match, a single advanced pattern
matching construct.
* Updated all libraries, tests and documentation to use these new syntax.
* Some work to provide improved error messages in surface syntax.

Fixed inductive elimination. Closes #33

Previously, inductive elimination could fail due to non-determinisic
matching in the reduction-relation and reduction over open terms via
reflection.

Split and reorganized package. Closes #14
...
Created split packages: cur, cur-lib, cur-test, cur-doc, similar to
other Racket packages, e.g., redex.
* Moved tests out of core and into cur-test
* Moved docs into cur-doc
* Moved cur implementation and libraries into cur-lib
* Added cur meta-pacakge that installs all of the above

Improvements to match; replacing uses of case

Renaming Σ to Δ

In dependent type system, Σ is normally the symbol for strong sums, not
signatures/declarations.
While Δ is sometimes used as an alternative to Γ, using it for
inductive signatures.
