Prior to this, the analytic fits data was all for twoF = 60, this
updates this and adds a tag to the filename to make it it clear

Use N=1000 for the recoveries and N=10000 for the test in noise

Issues:
1) If tstart and duration where not explicity searched over, a loop
condition would quickly send the duration to infinity
2) Fixed half norm definition

1) Changes the way the prior is built to be wider than the initial box
2) Fixes error where the F0 and F1 where always chosen in the middle of
the box

Rather than starting with the fully-coherent Vsize, this now starts with
the input Nseg0 (i.e. from the SC search). and works back to Nseg=1.
The user is then left to check the V0 value and whether the search is
appropriate or not. Applies the idea to the follow-up example.

Also adds data from directed study

1) Adds transient section text
2) Some spell-checking and general changes

1) Allows true 'silent' running by switching off tqdm and SFThist output
2) Generalise the check old run setup to take an arbitrary set of
parameters to check (provided) they are in the saved dict. Then adds
DeltaOmega and DeltaFs check
3) Pass through the log_table and gen_tex_tables options so that one can
switch off these outputs
4) Adds create_plots to FollowUp run
5) Simple reorder to Writer parameters to group amplitude parameters
