# changed cleanup to remove encapsulating quotes
# Description: Library used by modules. Do NOT enable
our $VERSION = '1.3';
# set of libraries to be used by these modules
# cleanUp - passed a delimiter and a string, does the following (delimiter can be '')
# chomps the string (removes trailing newlines)
# removes all text BEFORE the delimiter, the delimiter, and any whitespace
# thus, the string 'xxI Am x a weird string' with a newline will become
# 'a weird string' with no newline
# will also look for single and double quotes surrounding entire string and remove them
# if they exist
