Get the number of columns in a Large File object

Methods for fast access to large ASCII files.  Currently the
following file formats are supported: comma separated format (CSV) and fixed
width format. It is assumed that the files are too large to fit into memory,
although the package can also be used to efficiently access files that do
fit into memory. Methods are provided to access and process files blockwise.
Furthermore, an opened file can be accessed as one would an ordinary
data.frame. The LaF vignette gives an overview of the functionality
provided.
