*ComparisonExp classes duplicates

[JSBmanD]

Bug description

Currently there's a problem if you want to generate requests with variables - in every generated file "*.graphql.dart" will be StringComparisonExp, IntComparisonExp or any other comparators. When you will export these files in the library - you will have conflict of class names and need to hide all these duplicated classes with directive hide. Good option to solve this will be having these comparators in the library or generating additional file with them.
