Pull out the genotype data from a cross object, as a single big matrix.

1	pull.geno(cross, chr)

`cross`	An object of class `cross`. See `read.cross` for details.
`chr`	Optional vector indicating the chromosomes to consider. This should be a vector of character strings referring to chromosomes by name; numeric values are converted to strings. Refer to chromosomes with a preceding `-` to have all chromosomes but those considered. A logical (TRUE/FALSE) vector may also be used.

A matrix of size n.ind x tot.mar. The raw genotype data in the input cross object, with the chromosomes pasted together.
