1. Capabilities of Plugin
-------------------------

Every plugin should list it's capabilities -- that is what subrutines are available in it. Capabilities list for the moment are:
Options for tape:

* PLUGIN_PROGRAM_START (requires subrutine void at_start(void)): runs at startup
* PLUGIN_VESICLE_INITIALIZED (requires subrutine void after_vesicle_init(vesicle *vesicle):
   runs after vesicle gets initialized.
extra_plugin_path = "..." (OPTIONAL)

* PLUGIN_VERTEX_MOVE (requires subrutines:
vesicle bipyramid {
   nshell=23	
}

   ts_bool vm_hard_constraint(vesicle *vesicle, vtx *vtx, vtx *old_vtx)
   ts_double vm_energy_before(vesicle *vesicle, vtx *vtx)
   ts_double vm_energy_after(vesicle *vesicle, vtx *vtx)
   ts_double vm_new_state_accepted(vesicle *vesicle, vtx *vtx)
   ts_double vm_new_state_rejected(vesicle *vesicle, vtx *vtx)

vesicle properties {
   xk0=20
   dmax=1.7
   dmin_interspecies=1.2
   stepsize=0.15
}
