    EESchema sheet pin code improvements. · cfc3d6df
    Wayne Stambaugh authored
    * Change all code references to pin sheet and sheet label to sheet pin to
      more closely match the sheet pin object for improved code readability.
    * Change menu and tool bar text from pin sheet to sheet pin for improved
      user readability.
    * Moved sheet pin place method to sheet pin object source file.
    * Move last sheet pin stored state information into schematic frame object.
    * Add Doxygen comments for the sheet pin editing methods.
