Add support for arrays. #76

Closed skx closed 5 years ago

skx commented 5 years ago

This pull request will close #75, when complete.

In brief:

We've updated object/object.go to support an array-type.
We've added dim as a keyword
We've added tokens for index-operations [ + ].
We've updated get/set to handle array-indexes as well as raw-variables.

The initial four commits were erroneously made on master, and have been pushed to this new branch, which means we lost the history, which is a shame.

Happy with the state of this for the moment, but overall test-coverage has dropped.

Will release once we're back where we were.

  frodo ~/go/src/github.com/skx/gobasic $ ./test-coverage 
  95.7%

(Also need an example program, or two.)
