-#templatePage.py
-#
-#--Genenetwork generates a lot of pages; this file is the generic version of them, defining routines they all use.
-#
-#Classes:
-#templatePage
-#
-#Functions (of templatePage):
-#__init__(...) -- class constructor, allows a more specific template to be used in addition to templatePage
-#__str__(self) -- returns the object's elements as a tuple
-#__del__(self) -- closes the current connection to MySQL, if there is one
-#write -- explained below
-#writefile -- explained below
-#openMysql(self) -- opens a MySQL connection and stores the resulting cursor in the object's cursor variable
-#updMysql(self) -- same as openMysql
-#error -- explained below
-#session -- explained below
