Add location lookup functionality

[RoyIL]

As the title suggests, now that we have decided on a preliminary design, we need to add the ability to look-up a location in accordance with the way the weather API we are using wants the location. In a way, we need to find a way to bridge between the user-inputted location and the way the API wants to receive the location. The look-up functionality will be used in the main "logged-in" view created by @DavisKHuehn.

• Add the ability to look up a location in various ways and formats.
• Find the best way/format to store the location in our DB.
• Add functionality of communicating to the user when a location cannot be found.
