Object language

The object language (the language that we implement here) is a small subset of Scala. Currently:

P ::=	"object" N "extends" N "{" S * "}"
S ::=	"var" N "=" E ";"
|	N "=" E ";"
|	"print" "(" E ")" ";"
|	"while" "(" E ")" "{" S * "}"
|	"if" "(" E ")" "{" S * "}"
|	"if" "(" E ")" "{" S * "}" "else" "{" S * "}"
|	"{" S * "}"
E ::=	N
|	L
|	E "+" E
|	E "-" E
|	E "*" E
N ::=	variable names
L ::=	integer literals
