set.dir blastlocation

Mothur allows you to set the location of the blast executables directory globally in any command, but it would be much more practical if it could also be set by, for example, set.dir(blastlocation=/usr/bin), which is the default location when installing the blast2 suite on linux with apt. By the way, the set.dir command manual page names blastdir instead of blastlocation.

The blastdir parameter is used to set the global path for blast executables.
