Removes simplices from the simplex tree. Individual simplices are specified as vectors, and a set of simplices as a list of vectors.
remove(st, simplices)a simplex tree.
simplices to insert, either as a vector, a list of vectors, or a column-matrix. See details.
This function allows removal of a arbitrary order simplices. If simplex already exists in the tree,
it is removed, otherwise the tree is not modified. simplex is sorted before traversing the trie.
Cofaces of simplex are also removed.
If simplices is a vector, it's assumed to be a simplex. If a list, its assumed each element in the list
represents a simplex (as vectors). If the simplices to insert are all of the same dimension, you can also
optionally use a matrix, where each column is assumed to be a simplex.
