            Object that associates the wall piece template names with information about those kinds of pieces.
                       Expects placementData[templateName].templateData to contain the parsed template information about
                       the template whose filename is templateName. |

                 'templates' key), as well as the min and max allowed overlap factors (see GetWallSegmentsRec). Expected
                 to contain template names for keys "long" (long wall segment), "medium" (medium wall segment), "short"
                 (short wall segment), "tower" (intermediate tower between wall segments), "gate" (replacement for long
                 walls). |
