fixed

added: keyword "#BL_OUTPUT_STEP" is added in the PARAM.in to define the frequency of the output of the exported field lines

experimental calculations added for pitch angle diffusion coefficient. The implemented diffusion coeffcient is improved comparing the previous version. The code has to be cleaned.
In the particle mover: is dt is too small insread d(mu)/dt the parker equation is solved end mu set -1+2*rnd() qt the end of a time step

added keyword '#BL_POINT_IMPORT_STEP' in PARAM.in to define a step in importing points from the field line (to reduce the number of the points)

2. added: SEP::Diffusion::GetMeanFreePath()
3. GetTransportCoefficients() is become a function (before it was a
lamda)
4. modified SEP::ParticleMover_He_2011_AJ(): GetTransportCoefficients()
is not a lambda anymore
5. added SEP::ParticleMover_MeanFreePathScattering(): particle mover
where
    a) pitch angle scattering events are simulated assuming a mean free
path between the events
    b) the direction of a particle velocity after scattering is
distributed unifirmly in 4\pi
    c) between the event the equation of motion is solve accounting for
the streaming, cooling, and focusing (the same as in
SEP::ParticleMover_He_2011_AJ())

1. sampled particle evergy is converted from J to MeV
2. the field line is increased in PARAM.in
3. the procedure for generating the initial particle momentum is
changed: the momentum is generated uniformly in log(p) then that is
compensated by the appropriate weight correction factor

The model produces something meaningul faster then real-time on amps-gpu

sep_focused_transport-ih--fl-He__diffusion.input is the input file used for  CCMC 2022 SEPs simulation

modified SEP::ParticleMover_He_2011_AJ(): sampling of the rate of changes of the pitch angle and momenrum is changed

multiple improvements in the SEP model. The model seem to produce something meninful with ParticleMover_He_2011_AJ

amps-out.thread=* when modeling SEPs transport propagating along
individual field lines

the value of the pitch angle diffusion coefficient is output in the save file as the pitch angle distribution for various energy levels

energy groups

used with OpenMP, the thread parallelization can be done (1) on the
level of the individual particles, or (2) on the field line segments.
The switch that defines which one is used is '_process_mode'
