Check for algorithm argument in splicing_miso.
Separate out calculating the match vector, preparing for read class based solver.
C level: added row-wise normalization for matrices.
Added fast read-class based solver for single-end reads. Untested!
Fixed the 'marginal' sampler, if some reads do not match any isoforms.
Fixed a bug when not the 'reassign' sampler was used.
Fixed a bug in the 'classes' sampler when some reads do not match any isoforms.
Sampler: fixed a bug in the calculation of the number of reads in the various classes.
