updated readme's boost version
added a message to determine which libraries were being used
found out that boost has a installed called bjam. bjam has an option --layout which can take the form tagged. tagged adds -mt and -<version_number> to a library. if multithreading is on (which it is by default), it must find a library with the -mt tag. I was able to turn off multi threading for it to find the boost libraries installed in filespace/groups/cnerg/cyclus_dependencies. I'd like to leave the comment there for posterity. this set of commits closes #521.
fixes #521 by documenting newer boost requirement.
switched event class to use a tweaked boost::spirit::hold_any allowing
non-explicit construction instead of boost::any. 30% performance boost of
total inpro_low runtime.
speed up event class by reserving capacity for event vals
added shortcut to void* in any.hpp. Simplified hdf5 backend fillBuff
Added modified warning to any.hpp. added comment about event vals vector reserve
changed c cast to static_cast
Merge pull request #519 from rwcarlsen/hold-any

swap a tweaked version of boost::spirit::hold_any for boost::any in Event class

I don't believe there was an open issue to be addressed, so this closes no issues.
