document (sparse) data format

[3bst0r]

Please document the data format that the tsne model wants with type 'sparse'.
I tried a nested array like [[i_11,...i_1j],...[i_n1,...i_nk]] where i_rs are the indices of the set values but that did not work.

for anyone wondering, it seems to be [ [i1, j1], ... , [in, jn] ] where i,j are the indices of the non-zero values.
