/*
PseudoCode:

File Exists?
if found:
    open and read in all lines, replace attribute name/value pairs with new value pairs to be saved.
if notFound:
    Check for actionFlag = "CH" (Create Host)
	if CH:
		Create file, enter data, save.
	if notCH:
	    Return fail code, exit.

NOTES:  For create, will need to add fields for new Host ID#, name, age, sex, occupation and OCV factors.
