Taking my cpp and h file into Otani's test
May be incompatible with master branch.

Review diffs before merging.
Add, toString and Convert working.
Successfully ran all tests against Otani's tester
Changed error messages in multiply

Fully functional.
Corrected Otani comment on signs

Prof Otani wrote me back and said he does not want the sign altered
on rbn and lbn when they are passed into the add function.  Keep
the integrity of the data.
Added otani's version of toString to source files
toString converted for use without vector.
non-functional

has errors on runtime.  Explore tomorrow.
working without vector in convert

need to review other helper functions and clean up
token and vector refs taken out of convert

need to clean up compare and its reliance on vector
interim set of changes...non-functional

removing vector from add_abs
add_abs converted made vector free

need to work on sub_abs next
checking default editor

switched to nano for commit messages
vector eliminated from sub_abs

compare remains the only use of vector
still working compare

committing here so I can try an eperimental branch
where I use lexicographical compairson so I don't have to
iterate...etc
success on lex comparison for compare

error free test driver..time to merge
all references to vector removed

regression test passed successfully for all functions
time to run this .cpp against the boost test and re-submit
renamed makefile to avoid a name clash on merge
error free test on boost for merged master

need to check otani test
Final Version.

All testst pass...let's see how it's graded
