/**
* Constructor. Checks if the file has been uploaded
*
* The constructor takes $_FILES['form_field'] array as argument
* where form_field is the form field name
*
* The constructor will check if the file has been uploaded in its temporary location, and
* accordingly will set {@link uploaded} (and {@link error} is an error occurred)
*
* If the file has been uploaded, the constructor will populate all the variables holding the upload
* information (none of the processing class variables are used here).
* You can have access to information about the file (name, size, MIME type...).
*
*
* Alternatively, you can set the first argument to be a local filename (string)
* This allows processing of a local file, as if the file was uploaded
*
* The optional second argument allows you to set the language for the error messages
*
* @access private
* @param array $file $_FILES['form_field']
* or string $file Local filename
* @param string $lang Optional language code
