This is the main type for tropical cycles. A TropicalCycle consists of a Fan with an extra HashKey Multiplicities, which is the list of multiplicities on the maximal cones listed in the order that the maximal cones appear in the MaxCones list. A TropicalCycle is saved as a hash table which contains the Fan and the Multiplicities.
The object TropicalCycle is a type, with ancestor classes MutableHashTable < HashTable < Thing.
