DriftShell: decreased step size in FindBmRadius. Moved output to a verbosity level lower.

TODO: Track down errors under verbosity level >5 as something segfaulted here...
Lgm_B_Dungey: added comments/notes
ComputeLstar/Lgm_LCDS: Changed search plane to SM (from GSM) and added diagnostics
ComputeLstar/Lgm_LCDS: fixed structures used in setup/teardown for AlphaOfK. Improved diagnostics.
Changed search algoirthm in FindBmRadius().

The initial algorthim did an intial bracketing then a bisection to find the location where B==Bm.
In the outer regions of the magnetosphere, the initial bracketing could sometimes skip over the
root. To fix this, I added the ability to track local minima as well. Now, if a
zero bracket is not initially detected, the algorithm search the local minima
that were encounetered. Seems ,to fix some stabilityl issues for LCDS calcs, etc...
