Upgraded the tooltip styling (made it black with rounded corners). Began working on validator array functionality, in where multiple validators can be added for a single calculator variable. These are then automatically ran everytime the variable changes, and the red/green status and tooltip updated accordingly.
Made tooltips red to look like errors. Tooltips now display errors message associated with failed validator. Had to create a new qTip everytime I wanted to change the text as the content text change code didn't work properly.
