Work in progress.

Starts to create isFile.js.
Improves asString for modules.

All modules have the same “class”: module,
but different values.  Maybe?
Adds auxiliary file to tests.

printc.gct needs to be pushed to the web server if
tests are to run clean in the browser.
Moves t152_inheritsReturnObject back to tests.

This test now passes!
Also adds missing .out file for t15c
Adds stub io.grace

This file defines the types and has dummy bodies for the methods.
It creates a suitable .gct for the io module.
Adds objectdraw.grace.

This file was not in the repository!
Also adds it to the makefile and index.html
Turn off type checks with a pragma.

Adds the pragma to ast.grace
Removes osFile.grace.

This should never have been committed.
