a) Updated CMake files to run tests and properly import other boost dependencies
b) Improved custom expectation facility and added test for same
c) fixed error when checking wasn’t being done on assignment
d) fixed error where lower bound was assumed to be 0
corrections in cpp promotion
added make_safe_literal
separated integers from other types
dropped example91
updated CMakeLists.txt and Jamfile.v2 accordingly
Turns out that these changes should also better position us to handle other underlying types - but we're not there yet.
Added example for composition with other types - example boost rational and boost multi precision
Added performance test using boost multi precision
Many other small corrections
