Modify current plotting design to use more efficient tools such as pandas and numpy to speed up plotting time series. Currently the plot is dreadfully slow even for a reasonable amount of data values.

Enhancements include:

• Using numpy datetime arrays to store values instead of python list of datetime objects
• Use pandas to do statistical analysis for the stats page
• Change current limited host_subplot to fit the needs of the program. Use matplotlib.spines instead for creating multiple axes.
• Add Try/catch or Nullable tests after every query to the database
