Title: Methods for reading a column + checking if there is already a respective column

This PR introduces the function `Table#hasColumn`, which checks if there is already a column with a certain name. Also there is `Table#createColumn` which transforms various input into a column. Furthermore we tackle #63 via not overwriting existing functions anymore. To get the respective columns nevertheless one needs to use `Table#getColumn` or the shorter form `Table#get`.
