Add methods isctime and isdtime for LTI objects
This change makes
>>> sys.isctime()
an alternative to the existing function
>>> isctime(sys)
Its advantage is that it avoids checking the type of `sys`, and
is a little cleaner: LTI objects now know whether they are
continuous or discrete time, and the isctime() function no longer
needs to poke around inside the LTI object to determine this.

Log Message:
-----------
Implement c2d without slycot (fixes #23)
Conversion from continuous-time to discrete-time are now implemented
as methods of the TransferFunction or StateSpace classes. The
function sample_system() is still provided, and takes either a
state-space system or transfer function as an argument.
The implementations simply call the routine `cont2discrete` from
`scipy.signal`
This new organization into methods avoids some messy type checking in
sample_system(), and also avoids some unnecessary conversions between
state-space systems and transfer functions, which fixes #23.
