    Minor code improvements and coding policy fixes. · 45445dd8
    Wayne Stambaugh authored
    * BLOCK_SELECTOR class is not longer derived from EDA_ITEM.
    * Encapsulate BLOCK_SELECTOR class member variables and add access methods.
    * Move HandleBlockBegin() function from block_commande.cpp to drawframe.cpp.
    * Remove virtual methods from top level derived objects per future
      coding policy change.
    * Remove Doxygen copydoc statement from objects derived from EDA_ITEM
      since the comments are automatically copied to the derived object.
    * Removed copy and pasted Doxygen comments from objects derived from
      EDA_ITEM.
