/**
* Returns a list of hidden inputs which are extracted from the form attributes which can be extracted
* from the user's profile information in Drupal. The attributes which are used are marked as handled
* so they don't need to be output elsewhere on the form. This function also handles non-profile based
* CMS User ID, Username, and Email; and also special processing for names.
* @param array $attributes List of form attributes.
* @param array $args List of form arguments. Can include values called:
* copyFromProfile - boolean indicating if values should be copied from the profile when the names match
* nameShow - boolean, if true then name values should be displayed rather than hidden.
* In fact this extends to all profile fields whose names match attribute
* captions. E.g. in D7, field_age would populate an attribute with caption
* age.
* emailShow - boolean, if true then email values should be displayed rather than hidden.
* @param boolean $exists Pass true for an existing record. If the record exists, then the attributes
* are marked as handled but are not output to avoid overwriting metadata about the original creator of the record.
* @param array $readAuth Read authorisation tokens.
* @return string HTML for the hidden inputs.
