/** \page concepts TBB concepts
    
    A concept is a set of requirements to a type, which are necessary and sufficient
    for the type to model a particular behavior or a set of behaviors. Some concepts 
    are specific to a particular algorithm (e.g. algorithm body), while other ones 
    are common to several algorithms (e.g. range concept). 

    All TBB algorithms make use of different classes implementing various concepts.
    Implementation classes are supplied by the user as type arguments of template 
    parameters and/or as objects passed as function call arguments. The library 
    provides predefined  implementations of some concepts (e.g. several kinds of 
    \ref range_req "ranges"), while other ones must always be implemented by the user. 
    
    TBB defines a set of minimal requirements each concept must conform to. Here is 
    the list of different concepts hyperlinked to the corresponding requirements specifications:
    - \subpage range_req
    - \subpage parallel_do_body_req
    - \subpage parallel_for_body_req
    - \subpage parallel_reduce_body_req
    - \subpage parallel_scan_body_req
    - \subpage parallel_sort_iter_req
