This provides a GUI to import to the API

Usage - go to the url civicrm/csvimporter/import
NOTE
- No menu items are added - you need to add them
- you need to type in the entity you are importing to on the first screen - in a way the api recognises e.g ContributionPage, contribution_page
- My preference would be to put the entity name into the URL but something about the multipage form wouldn't work here
- So, I will probably add a setting so permitted entities are defined & loaded into the select box (at some point)

This extension is available as is where is. Unpaid support / upgrade guarantees are not available

As the Import classes in Core are heavily copied & pasted & it is hard to separate generic code from import specific code this
extension has 2 classes for each required class
#1) 'BaseClass' - generally contains code that would be ideally in the import base class in cre
#2) import specific code
