Continuation Core and Toolboxes (COCO) Code

added intermediate size test file for bandwidth reduction

added utilities subtoolbox to coco

new ToDo list

changed number of segments

added timing to test suite

new ToDo list

updated collocation toolbox to use coco_set and coco_get

- cleaned up and moved mpbvp to collocation
- default bvp solver is now subtoolbox of collocation;
collocation now has proper constructors
- renamed option "coll.multipliers" to "coll.vareqn"
- updated all toolboxes depending on collocation [pocont, hscont, imfcont]
- updated all examples using bvp or collocation
- added new script "svn_move_toolbox" for moving toolboxes and
renaming all toolbox files
- added *.mexglx-files fo ignore list
- new ToDo file

- new function coco_get to access settings for toolboxes in a tree-like way
- coco_set and coco_get allow access of toolbox settings using the prefix
as a path; settings are recursively inherited from the leafs to the root
making it possible to have more general and more specialised settings; in
particular, to set options for each instance of a multiply present toolbox
- cleaned up the toolboxes alcont, pocont and mh_imfcont; these toolboxes
now use much fewer files and use the new coco_set/get functionality; many
functions added with add_func are now local to m-files that add them
- new possibility of passing an 'empty' toolbox to coco; the whole continuation
problem can be constructed by the user, see example coneD; this is intended
for toolbox developers to set up and test problems prior to moving code to
toolbox constructors
- fixed a few bugs and removed 'x' from the permissions of all m-files

fixed computation of period-doubling curves
