Title: Target 1 : Seifert Matrix : Major changes

Major changes have been made after testing, the required array was considered wrong leading to disturbing inconsistencies. Some of them still exist for like input -1 4 1 4 1 5 6 the component matrix does not give out 4 6 5 instead gives out 4 0 5, the logical gap has been identified and will try fixing it.
2 inconsistencies have to be looked into :
1. with input like 1 6 1 6 there are inconsistencies , here the additional unncessary rows should be removed from the braidwordmatrix
2. the one mentioned above should be tackled.

For any other input the results are consistent and have been cross checked with
