making terminology consistent

[gfudenberg]

lattice length is alternatively called:

L:

  L,

• looplib/looplib/random_loop_trajectories.py

  Line 3 in 0ea23c8

  def exponential_min_loops(L, loop_size):

N:

• looplib/looplib/random_loop_arrays.py

  Line 5 in 0ea23c8

  def uniform_loop_array(N, loop_size, loop_spacing):

how about being explicit, e.g. lattice_length?

relatedly, we might benefit from reserving loop_anchors as a term for un-paired positions of left & right sides of loops. Left & right could then be left_anchors and right_anchors, which might also be more easily readable than l_sites and r_sites

currently in FRiP() this is called lef_positions:

looplib/looplib/looptools.py

Line 187 in 0ea23c8

def FRiP(number_of_sites, lef_positions, boundary_positions):
