class UI(object):

    Class UI is used to show the data in the terminal with library curses. It
    contains two main diffrent functions, one is to control the UI and show the
    message in the terminal, the other is to search the information and then
    transform it into a string varible called items[]. This can be showed or
    exported as a plaintext. These functions to fill items[] are PUBLIC.

    - Methods:
      - UI().run()              - Run the UI in terminal.
      - UI.draw_<symbol>_page() - Get the information of specific symbol

    - Variables:
      - UI().items              - The result searched from database.
      - UI().armcc              - ARMCLANG option.
      - UI().gnuarm             - GNUARM option.
      - UI().con                - Database handler.
      - UI().function_name      - Specific function name.
      - UI().data_name          - Specific data name.
      - UI().section_name       - Specific section name.
