friendly_since()

def uploads.friendly_since	(		time_type,
			since
	)

Takes a since and, if it is Run-based expressed as Lumi-based, returns the run number.
Otherwise, returns the since without transformations.

    if time_type == "Run" and (since & 0xffffff) == 0:

# this is simple, and works for now - if logging requirements change, I will write a logging class to manage logging

			message
	)

new_log_file_id()

def uploads.new_log_file_id

(

)

Find a new client-side log file name.

Note: This cannot use the upload session token since logs need to be written before this is opened.
However, this can be changed so that the filename that uses the token is written to once
it is obtained.
