* Make the library modular usable.
* Switch to library requirements instead of source. As source puts extra source in install targets.
* Update library dependencies.
* Add requires-b2 check to top-level build file.
* Bump B2 require to 5.2
* Change all <source> references to <library>.
* Move inter-lib dependencies to a project variable and into the build targets.
* Switch to /boost/test//included target for header only mode of Boost.Test.
* Update build deps.
* Change math dep real target math/tr1.
This test checks, wether solvers of order ord can solve the problem
x'(t) = 1 + t^p
for p<ord with a very high accuracy (10^-13).
This should be the case for linear solvers, see
https://github.com/headmyshoulder/odeint-v2/issues/145
for a discussion about this topic.
The Adams-Bashforth-Moulton stepper called the corrector step with the wrong time value, as pointed out by GregorDeCillia in Issue #144. This commit fixes this bug and adds a test to check the correct behavior.
