Changes in the UI

Here is the pull request again with all issues that we have discoused fixed.

>Why do you need to convert to mmol if the resource is already in mmol?
good catch.
the data is in mmol. we need to convert it to mg/dl. this is actualy what we are doing, however the name of the function should have been convertToMgdl. (Please note that the function does 18x) which is in the right direction...
