Internal references

Internal references are links between epigrams of the anthology. The relationship is symmetrical.

Many types of links are possible. An epigram can be the variation of another (and there are different kind of variation) or just have a vague link.

This is still work in progress ; the type of internal reference will most probably always be "default".
