Set Branch Mode

Specify which branch to take first in the branch-and-bound algorithm for decision variables in an lpSolve linear program model object.

set.branch.mode(lprec, columns, modes)

`lprec`	an lpSolve linear program model object.
`columns`	a numeric vector containing values from the set `{1, ..., n}` (where `n` is the number of decision variables in `lprec`) specifying which columns to set the mode for.
`modes`	a character vector composed of the strings `{"ceiling", "floor", "auto", "default"}` giving the branch modes for the decision variables specified in `columns`. Please see the reference for a description of these terms.
