switching to the use of tags

As i mentioned last week that we had two options to view the complex obs, first we tried to pass the view generated in the controller but it didn't work properly. The is a method called getHyperlink() which is supposed to return the link that shows the entire complex observation. But when we called it in jsp page, it returned the link to the encounter.

Since we had a second option of using a custom tag, we tried created a PreviewComplexObs tag in the openmrs.tld file and PreviewComplexObsTag,a taglib class that relates to the tag. Tyler did a fantastic job on this, so that we can call now css classes in java.Now, you can get the link of the observation.

Future work: Creating a thumbnail of the image and store it.
