NAME: lf_report.py
PURPOSE:
This program is a helper  class for reporting results for a lanforge python script.
The class will generate an output directory based on date and time in the /home/lanforge/html-reports/ .
If the reports-data is not present then the date and time directory will be created in the current directory.
The banner and Candela Technology logo will be copied in the results directory.
The results directory may be over written and many of the other paramaters during construction.
Creating the date time directory on construction was a design choice.
EXAMPLE:
This is a helper class, a unit test is included at the bottom of the file.
To test lf_report.py and lf_graph.py together use the lf_report_test.py file
