/*****************************************************************************/

/*! The Class WorlModel contains all the RoboCup information that is available
    on the field. It contains information about the players, ball, flags and
    lines. Furthermore it contains methods to extract useful information.
    The (large amount of) attributes can be separated into different groups:
    - Environmental information: specific information about the soccer server
    - Match information: general information about the current state of a match
    - Object information: all the objects on the soccer field
    - Action information: actions that the agent has performed

    The methods can also be divided into different groups:
    - Retrieval methods: directly retrieving information of objects
    - Update methods: update world based on new sensory information
    - Prediction methods: predict future states based on past perceptions
    - High-Level methods: deriving high-level conclusions from basic worldstate
