function _opigno_install_custom_fields in Opigno 7

This is a hack to circumvent the fact that we cannot easily install custom field types within the install hook. This is because the hook_field_info() is not called at that point, triggering a FieldException: Attempt to create a field of unknown type. This function installs the custom fields and sets a variable, making sure we only install it once. It is called in opigno_init().
