/* This function is used to check a list of pf names to verify they
are in the parameter space. It is useful for any program that uses
parameter files that cracks the pf space anywhere except up front.
That is, the pf space is a convenient place to store all the run time
parameters of any program and is a convenient way to pass a large
control structure. However, because flow can be complex it is possible
to have parameters that are only accessed deep within a program and
in these situations it is desirable to run a check at program initialization
to verify the required parameters will be there when required.
Normally a string variable will not cause pfget to die, but it will
here if it is listed as required
Parameters to be checked are grouped by type. Each numerical fields
can contain an optional range check. This is not allowed for strings.
Code below only checks int, double, boolean, and string variables. Because of
the complexity of Tbl and Arrs I thought this not worth messing with.
Furthermore, it is not unusual to have an empty Tbl list or Arr that
the program should handle correctly.
Function will die on the first occurence of a problem parameter.
It is void because it only returns if everything checks out.

/* This function computes theoretical arrival times and a slowness vector
(at the reference station for an array) based on a model and method
defined in a parameter file and using the generic travel time interface
of datascope/antelope.
Arguments:
///inputs////
stations - Associative array of MWstation objects used in
multiwavelet programs
refsta - name of reference station to use. The slowness
vector is computed based on a source location accessed
through the db pointer (see below) and the location of
the reference station. If the refsta is not found in
the stations array the first element of the sorted list
of stations will be used in an attempt to recover. For
most arrays this would be a minor error.
phase - name of seismic phase to compute theoretical times and
slowness vector for.
db - This db pointer MUST point to a single row of a db view with
the origin table joined as part of the view. The hypocenter
information is read with dbgetv passing this db pointer
directly.
pf - parameter space pointer. We search for model and method
fields from pf to get the interface right.
///outputs///
times - associative array keyed by station name of theoretical
arrival times (stored as double * s). If there are
problems computing any travel times they will be absent
from this array. When this array is used, be aware you
can't assume all the times are filled.
slow - theoretical slowness vector. If the slowness vector
calculation fails this is set to 0 and the refsta field
is set to "BAD". This allows the use of the slowness
vector without errors in a less than ideal way. The
BAD condition should be trapped.
Return codes:
0 = normal return, no problems
> 0 = count of travel time failures
< 0 = nothing was computed. Both slowness and times should be
assumed invalid.

/* Init function for uniform table.

The following keys are required to be found in pf:
int:
nx, nz
scalar double:
dx, dz
&Tbl:
uniform_grid_time_slowness_table
The later contains the actual tables. They are ascii tables make up
of nx*nz lines (x varies most rapidly) of the following format:
time, slowness, slowness derivative wrt distance, branch
The "branch" variable is a character key defined in location.h
Optional parameters with defaults:
scalar double:
x0, y0 coordinates of first point in table (default = (0,0))
strings:
Notice that this routine requires mixed units. dx, dz, x0, and y0
must all be specified in degrees. Everything else has units derived
from km and s. That is, time is is in seconds, slowness (p) is
assumed to be in s/km, and dpdx (slowness derivative) is (s/km)/km.
This was done because the input tables are ascii, and these numbers
are scaled to units that make sense to most of us. This format is
connected to a related program called taup_convert that writes
ttables in this format using the tau-p library.
Returns 0 if no problems are encountered. REturns 1 if a serious
error occurred that rendered setup impossible for this phase.
In the later case, register_error is always called and should be
handled by calling program.
There are some fatal errors that lead to die being called here from
things like malloc failures.
