* Added support for arbitrary data types rather than just strings * Added support for integer index-able arrays * Improve code coverage for kunstruct - kunstruct around 90% - helper at 100% * Update expansion.Expand method to preserve the original type of the variable * Ensure the int field such .spec.replicas can be used as a source in a first Deployment or as destination of a variable (in the second Deployment variable).
