test suite level01 errors

[millerta]

In preparation for release, need to resolve test suite errors in 11 directories. For some, lagrit exits early on exception, it is not obvious what the problem is:

All checks complete, 11 directories failed out of 41

1 Check Directory ./addmesh_add --------------------------
172 lines failed.

dump/avs/polygon.inp/cmod
cmo/modatt/-def-/-def-/ioflag/x
finish

Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation.

In the debug build that does not die and exit, this flag is included.

-ffpe-trap=invalid,zero,overflow,underflow,denormal

[millerta]

ignore exceptions for now.

See #73

Fix build instructions to include exception traps (ffpe-trap=*). Look into low-hanging fruit on compiler flags to remove some of the errors?

• [ ] v3.3.3: only trap exceptions
• [ ] v3.4.0 (?): address underlying reasons exceptions are thrown

test suites and scripts updated and working but Daniel's merge with Master seems to have changed some of the test suite directories. Terry needs to check this against current copy before release.
