Using extra column sizes
Assuming we would like to use 2, 3, and 4 column grid. iotaCSS uses 2, 3 and 6 columns by default. If we want our change
to affect both Size and Pull / Push utilities, then we should update the global iota variable that lives in Settings.Core.

$iota-global-columns:2,3,4;
Otherwise, if we only need this change to be applied in Size utility, we should update the local size variable for columns.
