Data refactoring.

I realized that when SPMF results were read a few mistakes were made and at the same time to correct this i had to fix the pattern placement algorthm
so i decided to completly remove it and instead use the "show itemsets" option of spmf it took a lot of work but now the system works

I also changed the way the load fonction work so that it doesn't reload the data for noting.

Add some style improvement to the code and fix all exsiting project by replacing them with a similar dataset
