    \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
