Implement proper column versions #6

Currently the col versions of all tests transpose the inputs and call row functions.

This behaviour is undesirable because of at least three reasons:

Transposing inputs takes time.
col-wise functions (like colMeans) are typically faster than their row equivalents
When inputs have different lengths the functions might throw a warning about rows.
