Creating a fully connected layer

fcl* fcls = fully_connected(input,output,layer,dropout_flag,activation_flag,dropout_threshold);

input: the number of input neurons output: the number of output neurons layer: the layer number n in the network (the layers start from 0) dropout_flag: should be NO_DROPOUT, DROPOUT, DROPOUT_TEST activation_flag: should be SIGMOID, RELU, LEAKY_RELU, SOFTMAX, TANH, NO_ACTIVATION dropout_threshold: 0<value<1
