convert_dtm

Presently, <code>tidylda</code> makes heavy usage of the <code>dgCMatrix</code> class.
 However, a user may have created a DTM (or TCM) in one of several classes.
 Since data could be in several formats, this function converts them to a
 <code>dgCMatrix</code> before passing them along.

internal

Implements an algorithm for Latent Dirichlet
Allocation (LDA), Blei et at. (2003) <https://www.jmlr.org/papers/volume3/blei03a/blei03a.pdf>,
using style conventions from the 'tidyverse',
Wickham et al. (2019)<doi:10.21105/joss.01686>,
and 'tidymodels', Kuhn et al.<https://tidymodels.github.io/model-implementation-principles/>.
Fitting is done via collapsed Gibbs sampling.
Also implements several novel features for LDA such as guided models and
transfer learning.
