As a user, I can obtain a brief summary in the end of the Test Case Importer process

As a user, I can obtain a brief summary in the end of the Test Case Importer process, with:

• total of (potential) Tests in the CSV
• total of Tests imported successfuly
• total of Tests partialy imported (e.g. some fields couldn't be mapped for example)
• total of Tests not imported at all

This will provide basic information of the importing process.

Note: if possible, links to the partialy and fully imported test cases could be provided.
