    \brief

    a semaphore is a variable or abstract data type that is used
    for controlling access, by multiple processes, to a common
    resource in a concurrent system such as a multiprogramming
    operating system.

    <b>Features</b>
    - SEM initialize
    - SEM resource manager
    - SEAM lock & unlock

    <b> Operation Code Flow: </b> \n
    -# SEM initilize
    -# Get resource
    -# Lock
    -# UnLock
