LSEQ: CRDT for sequences

This framework allows the developper to configure underlying components of its allocation strategy and to measure the size of identifiers generated (see package module). Available components are divided in 4 categories:

Base: Double or Constant (parameter departure base)
Boundary: Double or Constant (parameter departure boundary)
Allocation strategies: Beginning (boundary+) or Ending (boundary-) (parameters base, boundary)
Strategy Choice: Single, Round-Robin or Random (parameter(s) allocation strategie(s))

Of course, the framework also allows to develop custom components.

Run

The frameworks gives two examples of launching:

On synthetic sequences (Front, Queue, Both or Random)
On Wikipedia pages

Once again, custom synthetic sequences can be added, and other kinds of real collaborative edited documents complying with the provided interface can be added.
