During meal entry a user searches for their food

Description:
A user enters food and this dialogue searches the database for matching nutritional knowledge tickets from which a user selects their exact item(s).

Actors:
All registered users

Precondition:
A user has selected to enter a new meal and is met with this prompt.

Actions/Postcondition:
The user begins typing the name of the food they're eating and as they type a live search displays corresponding food listings in the nutritional knowledge database. From this list, the user then selects the closest match to the food they were eating, and that food is then used as the basis for their nutrient meal entry.

Multiple similar foods should appear when one types in a given food item such as 'bread'.

Acceptance Test:
A search should be carried out with special characters (appl3 $au!ce), non-food items (chair), and other outliers. The search should still function with fuzzy-logic to offer the closest similar food item available in the database.
