Extend mod-kb-ebsco API with a method to modify titles. It has to be a standard PUT method that updates title record identified by id:
The method has to be called from Title Edit screen (out of scope of this US):
The request body should be similar to "POST title" (mod-kb-ebsco-java\ramls\types\titles\titlePostRequest.json)
The module will transform the request to PUT Resource request to save the data. There is no specific method in RM API to modify a title and right now the UI uses PUT Resource to update title's data.
