CTYPENEW CTYPENEW Create New Instance of C Structure

Usage

The ctypenew function is a convenience function for
creating a FreeMat structure that corresponds to a C
structure.  The entire structure is initialized with zeros.
This has some negative implications, because if the 
structure definition uses cenums, they may come out
as 'unknown' values if there are no enumerations corresponding
to zero.  The use of the function is

   a = ctypenew('typename')

which creates a single structure of C structure type 'typename'.
To create an array of structures, we can provide a second argument

   a = ctypenew('typename',count)

where count is the number of elements in the structure array.
