Implemented rng::uniform and rng::binomial for single values, vectors and matrices. implemeted dropout layers and tested it. Also fixed the validation code. Before it used y one place, now it uses y_test as it should.
Started on regulaization in Loss.h. I need to refactor the matsum.h since I need a total sum over the matrix. Also matmul needs a elementwise matmul function, which is the next this in the ragulaization
