Extract Nested Block 1.1

Extract Nested Block allows the user to convert a nested block into a primary block inserted at the same position for each reference of the nested block (i.e. extracting the nested block from its parent), retaining the same scale, rotation, orientation and all other properties possessed by the original nested block. Following selection of a nested block, the program will convert all references of the nested block and then proceed to remove the nested block from the primary block definition in which it resides.
