* \brief regular honeycombs
|
|
*
|
|
* works with spherical and hyperbolic ones -- Euclidean cubic tiling implemented in euclid.cpp
|
|
* includes non-quotient spaces as well as field quotient and elliptic spaces
|
|
* hyperbolic honeycombs rely on bt:: to deal with floating point errors (just like archimedean)
