Namespace conflict for try_reading_model()

[scallag]

When trying to create a mesh using CS173, I experienced a seg fault. Looking at the core file, it appears the CS173 library is trying to call try_reading_model() from the CCA library:

(gdb) where
#0 0x00002aaabf2330e6 in try_reading_model ()
from /projects/sciteam/baln/CyberShake/software/UCVM/ucvm-18.5.0_07282018/model/cca/lib/libcca.so
#1 0x00002aab97e60c6d in cs173_init (
dir=0x7fffffff38d8 "/projects/sciteam/baln/CyberShake/software/UCVM/ucvm-18.5.0_07282018", label=0x7fffffff3860 "cs173")

#4 0x000000000040ab22 in ucvm_add_model (label=, label@entry=0x448cbf "cs173") at ucvm.c:484
#5 0x000000000040aeb8 in ucvm_add_model (label=label@entry=0x448cbf "cs173") at ucvm.c:485
#6 0x0000000000405d15 in main (ac=14, av=0x7fffffff5308) at ucvm-single_mpi.c:513

Upon further investigation, it seems that both CCA and CS173 have try_reading_model() functions. I think changing the name of one of these functions would resolve the issue.

It looks like there is a conflict with read_properties() as well between CCA and CS173.

#0 0x00002aaabf232130 in read_properties ()
