Bulk Import for providers

Write a utility that allows the user to upload a spreadsheet (some standard csv or tsv format) with two columns:

• provider identifier
• provider name

Include an option for what to do if the identifier exists already:

• overwrite existing provider
• show error message
  • in this case the whole list should be checked for this error before creating any providers

This will allow bulk creation of providers, e.g. if a ministry of health, insurance provider, etc, provides a huge list of providers.

We are now extending this to add the bulk data import from an XML file which is basically to extract data from a non relational object based data.
