JPGs of exported UML diagrams from the project.
Fixes #8.  On second thoughts I've moved the design folder up to the top

Bumped version number to 0.1.0 for the release.
Moved the version number along after the 0.1.0 release.
Added Selenium and implemented a basic test for the Index view which
searches for a term and checks that the search results have loaded. Also
amended the header to include testin-friendly ids.
Removed unused code in DrugSearchTest.java
