In freealg: The Free Algebra

## This file follows the structure of aaa.R in the free group package.

## Define some checker functions, and call them at the end.  They
## should all return TRUE if the package works, and stop with error if
## a test is failed.  Function checker1() has one argument, checker2()
## two, and checker3() has three.
