Reference is made to FIG. 1, which is a schematic block diagram of an example computing device, according to some embodiments of the invention. Computing device 100 may include a controller or processor 105 (e.g., a central processing unit processor (CPU), a chip or any suitable computing or computational device), an operating system 115, memory 120, executable code 125, storage 130, input devices 135 (e.g. a keyboard or touchscreen), and output devices 140 (e.g., a display), a communication unit 145 (e.g., a cellular transmitter or modem, a Wi-Fi communication unit, or the like) for communicating with remote devices via a communication network, such as, for example, the Internet. Controller 105 may be configured to execute program code to perform operations described herein. The system described herein may include one or more computing device(s) 100, for example, to act as the various devices and/or the components shown in FIGS. 2A-2B. For example, system 200 may be, or may include computing device 100 or components thereof.

Operating system 115 may be or may include any code segment (e.g., one similar to executable code 125 described herein) designed and/or configured to perform tasks involving coordinating, scheduling, arbitrating, supervising, controlling or otherwise managing operation of computing device 100, for example, scheduling execution of software programs or enabling software programs or other modules or units to communicate.
