## @deftypefn {Function File} {[@var{reg}, @var{prop}] =} parseparams (@var{params})
## Return in @var{reg} the cell elements of @var{param} up to the first
## string element and in @var{prop} all remaining elements beginning
## with the first string element.  For example 
##
## @example
## @group
## [reg, prop] = parseparams (@{1, 2, "linewidth", 10@})
## reg =
## @{
##   [1,1] = 1
##   [1,2] = 2
## @}
## prop =
## @{
##   [1,1] = linewidth
##   [1,2] = 10
## @}
## @end group
## @end example
##
## The parseparams function may be used to separate 'regular'
## arguments and additional arguments given as property/value pairs of
## the @var{varargin} cell array.
