updates

• Evolution routines were crashing when the limit for the maximum number of gluons had been reached. This has been fixed.

• The maximum number of gluons for the dynamic evolution option has been reduced from 600,000 to 400,000.

• The routine evolve_nostore has been added for situations with extremely large numbers of dipoles. Instead of storing them all, and then processing them all, this routine calls a processing routine for each dipole at the `tip of the tree' of dipoles, deleting the dipole from storage afterwards. It is configured so that the processing can take place at several values of rapidity during the same evolution. This routine is available only for fixed array compilation (dynamic dipole allocation would just slow down the program, without conferring any advantage). The routine is to be found and is documented in the file basic_src/fixed_array/evolve.f90.

• A similar routine, evolve_ns_trunc, stops the evolution once the processing routine returns a code indicating that it has sufficient information about the onium. Such a routine is useful in situations where the information required about the onium can be deduced without requiring all its dipoles to be present.
