filterNoSignal: Omits the variables with no information

This function will clean a dataset from the variables that have no or little information.

filterNoSignal(X, side = 1, threshold = "auto", verbose = FALSE)

`X:`	the dataset to clean
`side:`	side=1 means that variables are in the rows. Other than 1 it will transpose the dataset
`threshold:`	auto, will compute the first derivate of the median(sd)/x and will find an automatic threshold. When threshold is a numerical it will be used as a threshold and when is something else, will automatically be 0.
`verbose:`	print out information when TRUE (default:FALSE)
