adding automated modulefile configuration and installation to pcu

trying to fix sun compiler warning

(did I really just say that??)
trying to fix pgi compiler warning

std::map::at is a C++11 construct
fix compile error

caused by a3518cc
apparently the std::map::at
was used to access a const std::map.
Since C++98 doesn't give us nice
accessor functions for const maps,
lets forget about const correctness.
fix pcu and apf module out-of-source builds
still trying to silence size_t print warnings

so all was well until we got to a 32-bit freebsd
box which now complains that unsigned long is
too big a specifier for a value that is actually
just unsigned.
now we just cast whatever the heck it is to long
and use the specifier for long.
didn't use unsigned long since its longer to
type in the casts and signed still holds all sane values.
turn off modulefile creation in Trilinos

I think there is probably a variable name
conflict, maybe PACKAGE_NAME is a magic
Tribits variable.
Anyway, leaving this code on in Tribits
causes mysterious errors in cmake generation.
fix compile error

The %ld thing didn't work in scanf,
in that case just stop using size_t
and use long instead.
remove time(NULL) from random seed

1) the proper header wasn't being included,
so this was a compile error on some boxes
2) I really don't like consciously adding
non-determinism to the code.
SCOREC/core is not a crypto library, please
make your seeds deterministic between runs.
removed dead return statement
fix prototype warning from pgi
Squashed commit of the following:

add function to prevent swap/collapse with matches
comment explaining 2D swap topo check
Adjoint Weighted Residual (awr) module

initial commit
filling in awr::enrichSolution
the match freeze code doesn't need DONT_SNAP
fixed bug in layer top flagger

by checking every vertex with
the LAYER flag, the top flagger
was failing to find a number on
the apex vertex of pyramids in
meshes with height differences.
those will never be considered
top vertices, so restrict the search
to numbered vertices.
remove unneeded variable
fix bug in growth curve top finder

the previous algorithm would fail
to find some tops around layer
height changes
prevent snapping from affecting matched entities
