f1d338194e rewrite how importing works 
* Introduce the concept of packages. Closes #3
 * Add support for error notes.
 * Introduce `@import` and `@c_import` builtin functions and
   remove the `import` and `c_import` top level declarations.
 * Introduce the `use` top level declaration.
 * Add `--check-unused` parameter to perform semantic
   analysis and codegen on all top level declarations, not
   just exported ones and ones referenced by exported ones.
 * Delete the root export node and add `--library` argument.

   expression
