Generate a diff and a MAQL DDL script

This method generates MAQL DDL scripts that you can use to update a project model and returns the link to a polling resource that returns the diff with the MAQL DDL scripts.</br> The diff between the two models is represented by script operations that you can execute on the current project model to make it equal to the submitted targetModel. If no difference exists between the current model and its targetState, the returned list of update operations is empty.</br> This example simulates the generation of a MAQL script for the model included in the example response of the resource for viewing a project model. The target model contains one extra fact, fact.employee.age.
