Added the ability to use multiple modules in one file

gistfile1.js

let module = macro {
	case {_
		$name
			import $params (,) ...
	} => {
		letstx $name_str = [makeValue(unwrapSyntax(#{$name}), #{here})];
		return #{
			angular.module($name_str, [$params (,) ...])
		};
	}
    
    case {_
         $name
    } => {
         letstx $name_str = [makeValue(unwrapSyntax(#{$name}), #{here})];
         return #{
               angular.module($name_str)
         };
    }
}

let factory = macro {
	case {_
		  $name {
		 	import $iparams
			$($mname $mparams $mbody) ...
		 }
	} => {
		letstx $name_str = [makeValue(unwrapSyntax(#{$name}), #{here})];
		return #{
			.factory($name_str, function $iparams {
				var ret = {};
				$(ret.$mname
		  			= function $mname $mparams $mbody; ) ...
		  		return ret;
			})
		  };
	}
}

module foo import '$a', '$b'

factory myFactory {
	import ($a, $b)
	
	say (foo) {
		console.log($a);
		console.log($b);
		
		return {
			a: $a[0]
		};
	}
}

module bar import '$x', '$y'
    
factory anotherFactory {
	import ($http)
    
	getFoo () {
		return $http.get('http://foo');
	}
}
