The similar_direction function could be erroneous for corner cases, refactored it out. This also makes it a bit less dependent on infinite_line (cartesian)
…org#701) * reorganize some parts of orient2d for a speedup * replace array in orient2d with own clearly named type.
In C++03 mimic the trait with has_trivial_copy, has_trivial_assign and has_trivial_destructor.

EDIT: closed in favor of more reasonably sized PR: #739
This pull request contains the first part of my GSoC 2020 project. This code is still work in progress and there might be changes to the interface before the end of GSoC.
The project aims to implement a number of facilities that allow easy creation of fast and robust geometric floating-point predicates, such as, for example, orientation tests (Boost.Geometry currently has a 2d orientation test in the side-strategy). As of writing this, the pull request contains templates to
I intend to add
The usage of the various templates for the creation of geometric predicates is illustrated in the tests and the example.
This pull request depends on Boost.MP11, which depends on C++11 but has no additional dependencies. The code itself depends on C++14 because of certain constexpr features.
