Adding tests for show.
Implement show and print for all periodic matrix types and
perform minor enhancements of two functions.
Correct hrtrunc to accomodate several subperiods.
Minor corrections in documentation.
Minor corrections in pmrand, norm and isconstant.
Minor extensions.
Minor fixes and extensions.
Version bump to use a new Tagbot setting
This is the initial release providing implementations of several periodic matrix objects and for the basic operations with periodic matrices. Several computational functions as the periodic Schur form, eigenvalues of matrix products, computation of monodromy matrix and computation of characteristic exponents/multipliers have been implemented.
