dedccdbdae [formaulas][util] Define coefficient containers for computing series expansions 
The coefficient containers are defined as structs in
series_expansion.hpp file. They allow the caller to
compute expansions without specifying the size
for the output array.

1972bcda3e [formula][util] Pass boost::array to series expansion functions 
Using boost::array we don't have to explicitly provide
the template parameters.

d591d7a7bb [util] Use existing normalize_spheroidal_coordinates class for normalizing an angle 
- This should normalize the given angle in range (-180, 180].
- The function normalize is also moved from math.hpp to
normalize_spheroidal_coordinates.hpp where it is renamed
to normalize_values

2cba2fa83f [test] Calculate geodesic scale (M12) using high precision arithmetic 
Instructions for building GeographicLib are given here:
https://geographiclib.sourceforge.io/html/highprec.html

It requires the use of libquadmath package, which is present
in g++-7 by default. The cmake command used is:
cmake -DCMAKE_CXX_COMPILER=g++-7 -DGEOGRAPHICLIB_PRECISION=4 ..

Internally, GeographicLib makes use of float128 as part of Boost
Multiprecision library. To output full precision values, use:
std::setprecision(std::numeric_limits<float128>::max_digits10)

fe1b9ff8ba [test] Update geodesic scale (M12) in GeographicLib dataset 
M12 is calculated manually using GeographicLib. Previously,
GEOGRAPHICLIB_PRECISION was set to 2 (default) with series
order set to 6. The updated values are generated with
GEOGRAPHICLIB_PRECISION set to 3 and series order set to 7.

Build instructions are provided here:
https://geographiclib.sourceforge.io/html/install.html

Boost Geometry dataset is created with series order 2. Therefore,
the tests fail at all other values.

inverse geodesic problem, therefore, it is moved
to a more accessible location.
