TODO:
write conditions for yieldsTest()
improve termTest() and write conditions for it
improve termfigurationTest() and write conditions for it
improve successorTest() and write conditions for it
make condensedConfigurationTest() return the appropriate boolean
have Acceleration.act() return the number of times Lemmas were employed,
and have actTest1() and actTest2() verify that Lemmas were used
the appropriate number of times
add checks to stretchTapeTest()
This should be completed before issue #2.
