Navigation Bug Fix

The bug where the top left navigation button would crash on the search
page has been fixed.
Very Basic Error Handling and Validation

If a non valid stock ticker is not entered, a message is displayed on
the main page.  There is still no network connection validation.
Forms Styling and Final Touches

-Forms styling added to all pages
-Conditional formatting depending on stock price
-Custom icon and other polishing done
-A minor bug still exists where on the Calc page the Entry fields act
strange with decimal data types, when adding a number with a decimal.
