# Converter.new :output {|v| Convert value v here...}

# MultiConverter is used for cases when a property in the xhib file's property bag needs multiple
# properties in JS
# Example: {'frameOrigin' => "{123, 456}"} should give {:top => 123, :bottom => 456}
# Done by: MultiConverter.new([:top, :bottom], /\{(\d+), (\d+)\}/) {|v| v.to_i}
