Changes

*:The starter code supports empty objects and string literals, but it does not support adding fields or methods to objects. You can test your implementation on the provided test-fields.164 file, which also details what fields must support and what syntax you must support. ''This should be done now. '''However''', the string x[0]+x[1] gets evaluated Precedence is now correct as (x[0]+x)[1] instead of (x[0])+(x[1])well.''
