My first first showing my ability to create simple app using RoR/database/CSS/JQuery/AJAX technologies.

Use cases:

• user clicks on the grid and can create a spot that appears on the screen

• user can add a name for the spot (when no name supplied, the spot will have name with an ID number)

• spots can not interfere with each other

• user can move spots with drag-drop feature

• spots appear in the screen without page reload
